Dear aspirant,

For neet , ncert chemistry is enough for it. All the reactions in that book are more than enough for neet. But yes for organic you need to have proper hold of the mechanisms of the organic chemistry reactions. If you are clear with the mechanisms then its allright.

But if you are not good with mechanism then you need to solve some previous year neet questions to understand the mechanisms specially of those when a nucleophile will come into play or an electrophile.

Get hold of  the general organic chemistry which is the crux for all the mechanisms. Sn1,Sn2 reactions.
