thank you for being not one of these guys who try to embed loathsome jokes to their scientific videos. You are making a difference in lives of many keep up.
I, personally, couldn't understand the terminology he was using, so I couldn't quite understand the concept. I'm sure to those who understood the terminology, it was quite helpful.
which terminology? you may have to go back and watch previous tutorials in this organic chemistry series, or my general chemistry series! all if the information is there for you.
hi Professor Dave, i need some help...what would be a chemical equation for the reaction when hydrogen and chlorine reacts when exposedd to UV light to form fumes of hydrogen chloride.. i hope you have instragram to ask questions..
You're so great at explaining Organic chem! Thank you for your help! Please consider explaining step growth polymerization and chain growth polymerization in the future.
Love you pro dave, super helpful video as always. Nearly a decade and people are still watching these super helpful videos. God be willing, your videos will be put in time capsules and saved for future generations thousands of years away.
Went straight from Lewis Dot Structures to this video and I have no idea what is happening. Update: watched "VSEPR Theory and Molecular Geometry" and it's starting to make more sense.
I’m just curious person who looked up the benefits of blueberries and saw antioxidant helps free radical damage. I’m digging through free radicals online and only see CGI images , drawings and equations. I feel like in science we make things up through our perception to make sense of the world. We see how things works but try to make sense of it. Only limited through our human perception.
My journey: (A non-chemistry student trying to make sense of his life) For the first 50 seconds, you assume you are in some episode of star trek and someone is using technobabble to confuse you. You question if he's saying anything coherent. To your dismay, you can look up almost all the terms he's throwing at you in rapid succession. Momma didn't raise no quitter so I continue. Pausing and looking up terms every couple of seconds. Losing track of what he said earlier. By 1:40 I think I have looked up many chemistry terms to sort of understanding what he's talking about. I was wrong. 2 minutes I am now trying to figure out what is heterolytic cleavage. 2 minute 40. I am now hearing about covalent bonds. I scroll down to see if someone in the comments knows what's going on. I see that everyone other than me seems to know what the heck you're talking about. They say this video is even helpful. To my horror, it seems other people have been able to follow along this entire time. 4 minutes. I am busy looking at his face and wondering if he could play Jesus in a movie somewhere. Due to being unable to understand 60% of the words being said causes a significant drag on my tiny attention span. 4 minutes and 30 seconds. I want to throw a shoe at someone. WHAT THE HELL IS A DOUBLE HEADED ELECTRON ARROW?! A;LKJDFLA;KJKDF (incoherent babbling) 4 minutes 50 seconds. Holy crap... he said something that actually made sense... single ions... single arrows... Ok... Ok... 5:40 I am now going back to stock trading. Checking trends I consider buying google stocks for a 70 dollar gain each over the course of next week. Oh look! Letters are moving! These letters are turning into other letters and it has something to do with electrons. But now I have more questions... why are the electrons moving? Is one positive and one negative or something? 6 minutes: How would get a different 'species' of chemicals?! What do these letters mean?! YOU'RE ALIENS YOU'RE ALL ALIENS! "Now in terms of enthalpy (gotta look that up), you cannot predict whether a propagation step (looked up, only to realize it's also on the board) will be endothermic or exothermic (Looking this up will not give you chemistry terms) because it depends on the bond energies (now googling bond energies)." At this point gave up on the video with my hands in my face. Suggestion: look up another video to start before watching this one. I need a chemistry for dummies because I am no closer to figuring out what free radicals are.
I’m an electrician but use a Nac supplement and it’s written on the package that nac can help absorb free radicals. Is this a false statement? Thank you the questions open to anyone who can answer!
Hi, somewhere they mention that radicals are relatively unstable but can exist on their own while ions are relatively stable but cannot exist by their own. I find this statement confusing and contradictory. I would like to know what they mean with stability. Thanks!
could there be molecules ( organic or non organic) that are more stable if the electron is actually draged away from the atom? Maybe atoms that are actually more stable if they lose their electrons ? I have been wondering but couldn't find the answer
Well I wouldn't really call it the reversal of covalent bond formation, it's much more often that a pair of electrons from a nucleophile coordinates to an electrophilic center, so if we were to try to put things in those terms, heterolytic bond cleavage is still the culprit. But to more precisely answer your question, we do just end up with two atoms! A halogen radical is a neutral halogen atom. For other compounds it's different because they're not simply diatomic.
hmm those are different types of bonds, you mean like with coordinate compounds? if i remember my inorganic chemistry that's more about oxidative addition and reductive elimination, but it's a little hazy.
@@ProfessorDaveExplains Got it. Makes me wish I'd taken more science. But I'll keep working through and look up terms. So interesting and you are enthusiastic about the topic which helps the listener. Thanks for replying.
I skipped a one hour and 20 minute class due to illness. This video is less than 10 minutes and wow you explained so well!
Hope you feel better

H2+Cl2---->2HCl when the two elements combine in a single container the prodcuct when exposed to UV it explodes what is the chemical equation?
@@ProfessorDaveExplains
Which terminology? Terminology like "cleavage" of course. LOL.
it's amazing how he explains an entire lesson in 8 minutes and in a very simplified way!!!

I swear you have saved my organic chemistry assignment. Thank youuuu!!! xx
Thank u from Egypt
U have just saved a pharmacy student ❤️❤️😂
You are the reason I'm starting to like chemistry again
Thank you so much 😊
You have made organic chem so much easier to understand thank you
You mentioning about the bond order cleared my 2 year old doubt.
99% thumbs up. Shows a lot about the quality of education this dude imparts.
Free the radicals ✊🏾

You sir, are awesome! I like the way you explain things. The fact that you look like a really nice person also helps. :) Thanks!

this was illuminating ... i didn't get why the bond was homolitical break , i just assumed that it was !

Hi,
somewhere they mention that radicals are relatively unstable but can exist on their own while ions are relatively stable but cannot exist by their own. I find this statement confusing and contradictory. I would like to know what they mean with stability. Thanks!
Stability essentially describes reactivity. Ions certainly can exist on their own, as can radicals, and their reactivities vary.
I got sidetracked by the tattoo
Why we study alkyl radical?
Do these exist in nature?
What is experimental method to study these?
could there be molecules ( organic or non organic) that are more stable if the electron is actually draged away from the atom? Maybe atoms that are actually more stable if they lose their electrons ? I have been wondering but couldn't find the answer
Kindly make a video on oxygen radical , superoxide radical formation.
Another outstanding video
I don't know why i love you but i just do... you're a legend
Thanks
Thank you sir
Your vdos are actually very useful
I can understand your way of teaching very clearly sir you teach soo good !😊
Oooh....i love the intro song
Thanks....it help me allot to understand "free radical mechanism" thanks 😊👍👍now it is so easy...
You are awesome!!! so helpful!
ahhhhhhh finally! thankyou!😄
Hello prof.
Could you please tell why free radicals aren't attached at double bond position ?
I know this is stupid but are the electrons in a bond entangled
I understood all of that 🙃
i love prof,essor dave. you are the best professor, and i dont even have to pay you 1000 bucks a semester
Amazing!!
I'll vibe you for being mean to quiet ppl if you're being vibes at from somewhere else while holding my life in your future
Good
Wow such an interesting video!
😊

Hey. Could you do a vid on Electron Displacement Effects, if you haven't already?
Thanks a lot for be so Clear!And not making the stuffs so complicated😁
What is the difference between chlorine atom and radical? Both have odd pair of electrons? Are they same sir?
yeah a chlorine radical is pretty much just a single neutral chlorine atom i suppose! i can't think of any difference.
That tattoo is interesting
WE COST. DON'T be fooled by others titles for fountains of young folks in an old keyboard society of A with Bs: ( because )
This definitely isn't level 1 😂
I don't understand shit where can I learn the basics ?
Hey Prof Dave, What was that artificial a-a-a-a sound at 6:22?
just me stuttering, friend.
You helped me a lot. Thanks, Dave
Can u plzzz draw resonating structure for triphenyl methyl radicl
Nice sir,as we can say that free radical becomes in covalent bond and ion in ionic bond?
i'm not sure what that means! but radicals are not ions.
Professor Dave Explains ok sir

Do homolysis and heterolysis takes place in co-ordinate covalent compounds sir?
hmm those are different types of bonds, you mean like with coordinate compounds? if i remember my inorganic chemistry that's more about oxidative addition and reductive elimination, but it's a little hazy.
Wow!🤩

It's already hard to understand with the unfamiliar chemistry terms. I'd love a layman's explanation.
It's not really possible, you have to understand organic chemistry to understand what radicals are.
