Hi there! I'm Praveen, now at your rescue.
Well, Organic chemistry was once just a discipline which could only be mastered by memorizing the reactions. But, it is no longer true. It has become the most interesting branch of chemistry. In between, let me tell you what makes Organic Chemistry a way better. If I tell you to write down the products of a chemical reaction in Inorganic Chemistry, you take them right from your brain. But, when it comes to Organic Chemistry you take it from your 'LOGIC', because it is all logically made.
If you need to carry out a conversion, you need to learn the mechanism in which each and every reaction proceeds. Once you get that clear, go for a question. Like, conversion of nitrobenzene into benzene.
So, what will you do now! Basically, you have to remove the nitro group. First convert nitrobenzene into aniline and then convert it into a diazonium salt and treat it with ethanol. Done! It might be hard to beleive if I tell you, it came from LOGIC
