At 21:29, there's a mistake in the Saytzeff rule. The compound reacting with NaOH(alc) should be CH3CH2CH(Cl)CH3 [2-chloropropane]. I missed a Hydrogen atom at the end (Carbon No 1) Also, at 34:26, the carboxylic acid produced from hydrolysis of Propanenitrile should be CH3CH2COOH (Propanoic acid), I wrote CH3COOH(ethanoic acid) by mistake. Furthermore, at 34:35, the amine produced from reduction of Propanenitrile should be CH3CH2CH2NH2 (propyl amine), I wrote CH3CH2NH2 (ethyl amine) by mistake.

at 17:21 for production of halogenoalkanes you have mentioned 1) free radical substitution 2) electrophilic addition of hydrogen halides to alkenes (for this the reagent should be concentration hydrogen halides bcuz alkenes dont react with dilute HX) and furthermore but i think there is one missing which is... M) electrophilic addition of halogens to alkenes (condition is R.T)
He did mention it tho... And it's elimination, not electrophilic addition, with NaOH and an ethanol solvent, forming the alkene, a sodium salt and water

I don't know if you're a Philippine 9:58 (weaker) and 16:34 (occurs) or an Indian (the way you say carbocation) , guessing from the accent, no offence. Very helpful video, you're definitely a life saver! Btw, at 16:48 is that supposed to be CH3COOH (ethanoic acid)? It's written HO1C-CO1H
Yes! That should be enough. But i’d suggest doing all variants from 2021, specimen paper 2022 and feb march 2022 if you have the time. Since the exam tomorrow will follow the pattern from these years. I have them uploaded in my channel if you need some help. Good luck!
hi the chemistry mcq paper did not go well and I dont think i'll be able to secure a good grade. Can you please tell me how other students found it and what they think the threshold will be? How did you students find the paper 2? what will be the overall for both p1 and p2? I'm so sorry for stressing you
Hey! It’s fine. Everyone is saying that both p1 and p2 were a bit more difficult than usual. So don’t worry. The threshold will surely be lower than normal. Focus on your next exam.
Yes! Thank you for pointing that out. I actually plan to make a separate video on IR spectroscopy, mass spectrometry and NMR spectroscopy soon! Keep your eyes on the channel
Hello. For elimination, ethanolic naoh, you could actually check the mark scheme for M/J 2021 variant 21, they mentioned ethanol+heat (under reflux). So you could mention it if you want since its correct. Same goes for hydrolysis of halogenoalkanes using naoh(aq). In the syllabus content reflux wasn’t mentioned thats why I didn’t include it in the video. But you’re right!
@@CAIEPapersSolved Thank you so much, sir, you are awesome GOD BLESS YOU !!! One more thing sir, I will be grateful if you respond, when we react alcohols to form halogenoalkanes is HX a gas or aqueous? Since in past papers they sometimes put HI (g) and then sometimes Concentrated HCl? What do I do in these situations?
Typically HX is gaseous, but sometimes they but aq. This is because they usually get HX by reaction NaX with conc. H2So4, which occurs in situ(inside the reaction vessel) and with heat under reflux, so it tends to be aqueous. But I think its safest to give HX(g) if its standalone and nothing else is mentioned.
@@CAIEPapersSolved thank you so much sir, I was wondering then it I put HX aqueous and under reflux would that be considered wrong and I will be penalized?
Does this cover all of organic chemistry? The exam is in a couple of days and i cant focus on reading so this video is all i have other than the past papers I'll solve
@@CAIEPapersSolved I see, thanks! By the way, what do you mean by K? For example you mentioned KSO4 in the formation of haloalkanes by reacting HBr with alcohol, and you mentioned KCN while explaining nucleophilic substitution

this is the best video on AS chemistry. it is short and extremely effective. prayers to you sir!
Glad it was helpful! ❤️
I'm not see it
watching this few hours before my exam and this has been really helpful thank you very much
watched this like 4 times so I hope I'm ready for chem paper 2 today! Good luck everyone and thank you sir!
Best of luck!
Howd you do?
Will u ever make one for inorganic in the same pattern?
That would be really helpful for the upcoming m/j 24 exams
This video is really good, it covers almost everything you need. I 100% recommend.
This made organic chem more understandable and interesting , exams next week , thnk you for this video
Really helpful sir! You're videos are well explained and you make concepts easier to understand. Kudos, kudos to you and all your hardwork. A real gem
Thanks for the appreciation ❤️
Subscribe to the channel for more content in the future! Good luck for your exams
Best summary vid for organic chem!
Appreciate it, bro. You are the best!
at 24:27 why does P+Br2-->PBr3 where is the third Br coming from? I have chem p2 tmr pls reply if u can thank u sm for ur vids!
thank you for the explanation sir, concise and well explained!
could you please send the notes too, sir?
Thanks so much, i was looking for a video exactly like this to refresh As orgo before i start A2 orgo 🙏🙏
If I manage to get good grades bcz of this I owe you my life
Thank u so much sir never give up on this channel it is so helpful
You're welcome!
Sir could you upload videos for physical and Inorganic for both AS and AL. I found this extremely helpful. Thank you!
Yes, soon!
Really helps before the real exam!
Thanks a lot👊👊
Happy to help!

Very helpful video, you're definitely a life saver! Btw, at 16:48 is that supposed to be CH3COOH (ethanoic acid)? It's written HO1C-CO1H
Hahaha, I’m actually from Bangladesh.
Also, at 16:48 its actually HO2C-CO2H, ethanedioic acid. Its a dicarboxylic acid. My 2 seems like a 1. My bad.
Hehe I am from BD too😅
Thank you so much sir, it is for u i've learned all of as level organic chemistry!
sir i have done past papers from 2017 to 2022 but only varient 2 exluding feb march for MCQs.... so is that enough assuming i have exam tmrw?
Yes! That should be enough. But i’d suggest doing all variants from 2021, specimen paper 2022 and feb march 2022 if you have the time. Since the exam tomorrow will follow the pattern from these years. I have them uploaded in my channel if you need some help. Good luck!
Do you some sort of coarses or tutoring separately (not these videos) for students of as n a2?
Yes. Please contact me here tasir.haque.02@gmail.com
Goodluck to those writing next week 🙏

Thank you
Pls do physical chemistry too
Amazing Vid... thank you sir
🙌🙌👏
My pleasure
Sir can you please do a video on infrared spectroscopy? I think it is the only thing missing, thank you so much for everything!

@@CAIEPapersSolved For sure sir, Thank you so much!
Thank you so much, but sir, doesn't the reaction of halogenoalkanes with Naoh aqueous and the Naoh ethanolic require heat under reflux?
Hopefully you respond soon sir!!
