You have my upmost praise, thank you very much. Videos like these will always continue to help future generations of chemist. You've made this topic seem like a breeze and concise. Once again, thank you
You explain this so well. I have been studying A-level Chemistry for 3 years now and have never really understood mechanisms till now. You make this all look so easy! A big shout out to you for making these videos 👍👏
This video was helpful.I will share it with my friends and even teachers in school.I would like you to post a video in which it shows the reagent and condition needed for all the organic reaction in A level. Thank you Sir,
+Priyansh Gujarati Thanks very much! I was considering this a few months back and working out how to come up with a neat way to run through it. Now it has been requested I will give it some more thought! Thanks for your support. 👍
I hate that...., A level questions are hard as **** book has 0 explanation about the concept/ way and my teacher is lazy as a pig... You should make a book having your videos
Please reply as soon as possible. You said that if the solvent was ethanol then there would be an elimination reaction. However for your nucleophilic substitution video you said that ethanol is a condition for nucleophilic substitution with cyanide ions. Im very confused. Either way, love your videos man
+Cookie Pink No problem at all! I have daily multi choice questions for AS Chem on twitter follow @allerytutors to get them. Good luck with your course!
On the diagram (on the right-hand side), shouldn't it be CH3CH2CH2OH instead of CH3CH2OH for the nucleophilic substitution example? Amazing explanation, by the way.
Hi, thanks for the video, seriously really has helped me understand this so much. If you dont mind i have a question, at 4:20, the C-H bond is being broken as H is being donated a lone pair, so why don't we show this by a curly arrow from centre of covalent bond C-H to C; we seem to show that for C-Cl but not for C-H ; can you explain why?
Thank you so much for these videos-! I've got my AS mocks after Easter and they've been super helpful. I just wondered, if you have an elimination reaction between bromopropane and sodium hydroxide, will the products include (H2O and NaBr) or (HBr and NaOH) and why?
If its dissolved in an ethanolic solvent then doesnt that mean its nucleophilic because in your other video of nucleophilic sub with NH3 the conditions were warm,ethanolic solvent and excess NH3? im confused
At the end of the video where you're explaining the geometric isomer formation you say E/Z, can you not say cis/trans due to there being a hydrogen atom attached to both carbons in double bond? Or am I confusing the concept? Thanks SO much for these videos btw
Thank you sir for the explanation :) , pls do reply when you are free. You've mention in the video that there will be equal chance of forming the isomers ,but wouldn't there be more but-2-ene formed ??because it is more stable than the but-1-ene due to positive inductive effect of alkyl groups
Why does the the product of nucleophilic substitution have only 2 Carbon atoms while the original haloalkane and the product of Elimination have 3 Carbon atoms ? A quick answer would be extremely appreciated and thank you very much for your hard work and dedication to help students.
A Level Chemistry Revision Videos The halide ion would react with the metal that would have been bonded to the OH- at the start of the reaction. This could be sodium for example. We don't include this in the reaction as sodium ion would be a spectator ion and hence not directly involved in the main reaction. Hope this helps!
laurenkellyg No problem! Please share the video to others who you think it will help too. The more people it will help the better! I have also started a podcast which may be of interest to you, just click the link at it will take you there www.allerytutors.libsyn.com/

So nice of you
Stuck in quarantine but I still have to do an organic test to send to the teacher. This really helped!
You explain this so well. I have been studying A-level Chemistry for 3 years now and have never really understood mechanisms till now.
You make this all look so easy!
A big shout out to you for making these videos 👍👏
have my CIE in three days and let me just say you've put my college to shame. great video!
Good luck with the exam! Not long now then! Please the videos help to supplement what you get at college.

@@AlleryChemistrydid you get round to doing this? I can’t find a good summary anywhere!

This is amazing, understood it really well
Brilliant!
Thank you so much reading from the textbook was hard to understand, but you made it so much easier to understand.
You are a lifesaver!! thank you so very much! :)

Please reply when you can.. Do we heat the reaction mixture under reflux for elimination?
Yes we do.
Great video! Thanks

Heh. I take it the video was useful!
Yess!!!
Excellent

A quick answer would be extremely appreciated and thank you very much for your hard work and dedication to help students.
This reaction have conditions please explain these conditions
What is the attacking species attacking the halo alkane? Is it a nucleophile? Electrophile? Anything like that?
its a base
What happened to the extra "CH2" when the reaction was in aqueous solution?
I think in 5:46 that is H-O-H, right?
Oh.. You are telling that there will be H+ combined with other Halogen group element
Jamba Jamba Yes the H+ ion will react with the OH- to make water.
