I tell students that when electrons are spin-paired, they are in a stable relationship. They can get excited into an "unhappy state". This are great videos for our students to learn bonding!
Great video, the best part was when you noted the scrapping the math jargon. Thanks for putting yourself in other people shoes and reflecting on your knowledge in your own time, much appreciated
I absolutely LOVEEE how you explain every single topic !!! Thank you so much you don’t know how much people you are helping with explaining such complicated things in the easiest way. You are amazing ❤️❤️❤️
Alongside a beautiful voice, that was such a brilliantly simplified illustration. Pleasantly clarified the whole mystery of a Molecular Orbital existing in 2 forms at the same instant. Thank you, ma'am. Wish the world had higher intelligent beings like yourself to question the basics and have a broader outlook. The Big Picture. LOVELY
I have watched several videos to try and understand this concept, and yours is the first one that clicked! I finally get the concept of bonding and anti-bonding molecular orbitals- thank you!!
Hi Leah, thanks so much for your videos they really helped me get into my top choice university undergraduate program. All going well I'll start at Oxford in October. Keep up the awesome content!!
What I've learned halfway through the video so far! There are atomic orbitals, which belong to unbonded atoms, and molecular orbitals, which are shared between bonded atoms. Within molecular orbitals, the electrons can either engage in constructive interference or destructive interference. This can also be described as lower energy, stable bonding orbitals, or higher-energy, more unstable antibonding orbitals. And... time to watch the next half of the video! :)
Part two of the video! Sigma bonds are simple overlaps, pi bonds are a different shape above or below the atoms. They have a node in the middle where the pi electrons do not go. The antibonding pi orbitals have a big node/separation between them, making them higher energy, whereas the bonding pi orbitals overlap and have a tinier node. It's like a relationship. If they are angry and high energy and separated they are antibonding and there is no overlap between the pi orbitals and they are unstable. It's like the pi electrons are only on one of the two carbon atoms, giving them different charges and making them unstable. If they have lots of closeness and no distance between they are happy and cuddly and close and stable and low energy! The pi electrons are both equally shared and there are no partial charges. And... time to learn about HOMO and LUMO! Thanks for another great video Leah.
Electrons: a romantic comedy. Seriously, it makes me more confused when professors bring up MO theory , antibonding orbitals, etc, but don't explain how it's applied to conjugated /aromatic systems behavior...it drives me bonkers....makes everything more confusing. I needed MO theory in plain English and you delivered big time :)
' double bond in C2 consists of both pi bonds because of the presence of four electrons in two pi molecular orbitals. In most of the other molecules a double bond is made up of a sigma bond and a pi bond' can someone explain this a bit simpliefied , does carbon molecule have 2 pi bonds between them because it have 2 electron each in bonding pi orbital , and no extra electrons in bonding sigma orbital and antibonding pi orbitals
The carbon-carbon double bond shown in the second example of this video has a single pi bond and a single sigma bond. The pi bond is made of p orbitals that sit both above and below the sigma bond, in a single plane. For help with questions like this and more, I recommend joining the organic chemistry study hall.

You are an amazing teacher. The way you teach us is very simple and easy to understand. I found your channel and very thankful to you ♥️. I want some more videos from you other than organic chemistry, like other chemistry topic. Your all videos of orgo are just love. You helped us lot. You deserve more than this. Always support and love for you ♥️. 🤗 Looking forward for your response. 🙂
Antibonding is when the electrons have very high energy and separate from each other rather than forming a bond. Meaning, they don't exist in the region between the nuclei where you'd expect to finding bonding electrons. I like to think of it as a couple that is very angry with each other and break up
Constructive interference means that the two waves that are in phase add together to form a giant wave and conversely destructive interference means that the 2 waves which are out of phase are cancelling each other out and you get no wave so we can think of an electron as wave or a particle.
Heyyy I love the explanation and I’m surprised to see that you have literally replied to every single comment. You really care about the viewers. Well I have chem final in 1 day and I’m super scared. 😢 But yea keep us teaching ❤❤❤
I love to stay in contact with my viewers! Thanks for watching, and best of luck on that Chem final! If you find you're looking for more help, I recommend joining my organic chemistry study hall. Details: leah4sci.com/join or contact me through my website leah4sci.com/contact/
@@Leah4sci well I will see in my next year(senior rn I’m a junior)cause rn after this final I will have to prepare for other finals too. Thank you for your support and efforts ❤️
10:35 it looks like jump rope. The bottom molecule has those blue "ropes" both going clockwise or both going anti-clockwise so one comes down while the other comes up and they entangle and bond. The molecule at the tope they are spinning in opposite directions so they smack into each other and repel.
Hlo mam your teaching method is awesome and it helps me to revise concepts fastly and easily why not you start teaching for Indian exam JEE please ,and lots of respect and love from india♥️♥️♥️
Can you explain SO³ to me? Is it shaped more like a shuttlecock or do the oxygen flare out to a more perpendicular shape, when they are compared to the Sulphur-S lone pair axis?

I sort of like this, but don't understand why there can't be one electron in each hydrogen molecule orbital. It might simply be an unlikely and essentially unstable configuration, no more stable than two separate hydrogen atoms, so just the same as having both electrons in the antibonding orbital.
When the 2 hydrogen atoms each have one electron in their respective orbitals, they are lone H atoms, unstable due to being unpaired. However if they come together at high energy you get the antibonding molecular orbital (vs the single electron atomic orbital)
Just to clarify madam, do anit bonding and bonding orbtials happen or exist at the same time in the same 2 atom? Eg. If i have 2 Li atoms will their bonds have both antibonding and bonding orbitals at the same time?
can i ask a quastion? why antibonding has a higher energy level than bonding? i already search article but i cannt understant can u explain to me? Thx a lot
It has to do with the presence of the node between the nuclei of the two bonding atoms. The antibonding orbital is higher in energy because of the decrease in electron density between those nuclei. In other words, the electrons have less freedom of movement in an antibonding orbital and remain partitioned to either side.
Can someone briefly explain hyberdrization? I thought i understood it (2 bonds for sp, 3 bonds for sp2, 4 bonds for sp3) but there seems to be exceptions, so i'm not really sure why those happen
@@Leah4sci i was asking peoples in the comments section, that if there are any jee aspirant who are watching your videos. Lemme explain, JEE is one of the most toughest examination in the world, many students (~1 million) in India🇮🇳 appears in it. I'm too a Jee aspirant. And your videos are helping alot, this concept was harder for me to understand from my teachers, but you made it clear to me, Thanks ma'am for your videos.

haha yup! I find that if you given chemistry/reactions human characteristics, everything suddenly makes more sense. Glad it helped
That was my same problem when I was taking Orgo. They always bring up anti-bonding and bonding but never explain it in essence.
Definitely deserved thumps up
thanks :)
you are seriously saving my a$$ rn tysm

antibonding always seems counterintuitive, that node makes sense though because the signal or wave can be continuous still even if it cycles
