Hi there,

Every chapter in the physics, chemistry and mathematics is very important such that nobody knows what type of quesrion arises in the Jee main examination. Also, the difficulty of questiin paper of JEE mains increases every year so there is assuring that this topic will not come or this will surely come.

See, it is you who need to understand and prepare the whole course and revise them on regular basis. Prepare well because the competition is very high.

I hope you understand.

Wishing you very good luck:)

Dear aspirant,

The chapter in chemistry mentioned by you is a very important one and you can be rest assured that one question will come from this topic and if it comes then 4 marks will be a bonus to you if you properly memorize this topic.

Like chemistry in everyday life few more topics like polymers , biomolecules are very easy topics and should be covered very efficiently.
