U
Unacademy user
very useful video sir........ please continue.
I have watched all of your videos on alkanes but, I just wanted to ask you whether we have to remember all the these or we can just refer NCERT (is it enough for mains?) Because now there's no time in hand and I've been following NCERT.Or do you think that what you teach in these videos is also important for JEE Mains? By the way, thank you!! U've been teaching so beautifully, cramming has stooped, really feeling interested in chemistry. Pls reply fast.

in Qus.5 when carboanion is form why it attack at opposite carbon but there is possibility to attack adjacent carbon and remove Cl to form double bond and also angel strain less

Because elimination occurs when we've a strong base. A weak base gives substitution.

Agar pas wale pe double bond bana liya to angle strain badega na ...single bond mai angle strain ki koi chinta nhi

but we can dimerise it to reduce angle strain @amberjoshi
Thank you bhaiyya!! I also have the doubt that in the 2nd question,you removed all the cl- at once,but in the last one,you took them out one by one!!why so?how will we get to know about this in the question itself?
