Kothao pacchilam na reaction ta...hothat e pelam.😊... age onek video dite valo valo...ekhon quantity kome gache

[@pritamde1634]

Dada at 3.28 sec er question a jodi epoxide ta down side a thakto to nucleophile ta methyl carbon er nearest epoxide carbon a attack korto.,....bolchi methyl er place a onno bulky group thakla ki oi aki position a attack korto na tokhan twisted boat Diya jeto?

I really appreciate your effort in making these videos. Do you have an option to record with better audio? It felt as though only one of my earphone is functional when I was watching this video :(

[@Chemistrylover]

I will try to improve 😅

[@ahallyajaladeep9963]

Thank you. That would be great :)

[@bhagyashripimparkar474]

Ï m always confused in this now ï m not.Thank u professor

[@godson200]

Is this part of jee syllabus.. I think you might be knowing

[@Chemistrylover]

No, it's not.

[@godson200]

Mera coaching ka teacher hum ko ye sab padhate h.. Bohot pressure badh jaata h.... Oxiranes are not even part of ncert.. Pata nahi kya dikkat h inse

[@shalnishalni2104]

Sir from where we do question practice for stereochemistry

[@Chemistrylover]

Previous year questions

[@shalnishalni2104]

Sir, for complex molecule i get confuse to identify distereomers and enantiomers so what can i do by which i get clear my concepts

[@Chemistrylover]

U can look at nasipuri,,,,several examples are there

[@Aniaha-]

Hmm same question

[@bellamkondamadhavi7781]

Sir please explain inorganic chemistry also

[@CloudwithSK]

nice

[@satrajitindu5234]

The transition state which you are calling "boat like" is actually "twist-boat like" and your drawing of the half-chair conformations are also not very correct. The epoxide carbons and their adjacent carbons on either side should be on a straight line (denoting the same plane, as u correctly mentioned)

[@Chemistrylover]

U are completely correct, but u should consider the context and plot of the video! U need to watch my more videos, see every time we don't depict the whole details of mechanism while solving a problem, because competitive exams are not to show how much u learn, rather u have to know to solve questions in minimum time. For example ue don't show the tetrahedral intermediate in each and every reaction, that doesn't mean it doesn't go through that intermediate. Hope u understand my point. Thanks for ur feedback.

[@satrajitindu5234]

Chemistry lover : i do understand the scope and point of your videos. I have watched many of your videos and hence i make my point. What you mentioned about the transition state being boat like is wrong. It should be twist boat like. While the focus may be on solving questions quickly, one must not give wrong information. There are wrong ways of arriving at a particular correct answer and in my humble opinion, they should be avoided.

[@Chemistrylover]

Yes it's twist boat, I think I have drawn "twist boat" and not boat, I may called it boat, that's a slip of toung! And I apologise for that unintentional mistake!

[@VipinSingh-er9rh]

He wrote twist boat in the video. So what’s the matter.
