Subjective Approach
You can’t learn organic chemistry because there’s too much of
it. You can learn trivial things like name of compounds but that
doesn’t help you to understand the principle behind the subject.
You have to understand the principle because the only way to
tackle organic chemistry is to learn to work it out. That is why we
are first providing you some questions so that your understanding
about the topic should be increased. These problems should be set
you on your way but they are not the end of the journey as you
begin your journey to understand organic chemistry.
The problem would be of little use to you when you could not
check your answers. For the maximum benefit, you need to solve
all the problems without looking the answers. Then you should
compare your answers or suggestions with ours before going to
next chapter. If any answer is mismatch then darken those question
numbers with red pen and again have a micorscopic look over it
and its theory and correct it before proceeding further. Here starts
the first set of 55 questions
1. What are the general types of organic reactions. Comment over
it by taking simple alphabets without any reaction.
2. Wha t is rea gent. Na me the types of reagent generally we
encounter in organic chemistry.

example which violate this rule.
