Hi Guys,

Welcome back to your own site India Study Solution

Starting from today we will be bringing you 20 sets of new test series of a new chapter from organic chemistry (Please scroll down to find NEET and JEE syllabus for this chapter).

As you are already aware each set of India Study Solution test series contain very carefully selected, 10 most important questions with their hints & solutions (given at the end).

This is a very important chapter and so, we would request you to please bookmark this site or if you have not subscribed us yet then please subscribe before you forget (it is free) so that you get information whenever we publish more questions on any chapter either from Physics, Chemistry, Biology or Mathematics.

Hope it would help you to learn and enhance your confidence to prepare for NEET, JEE (IIT), AIIMS, BHU, COMEDK, other MBBS Admission Tests, Engineering Entrance Exams, NEST. So, friends without wasting any time let us start -
