Benzene Reactions, Arene Reactions, Methylbenzene Reactions - Organic Chemistry

In this video we go through the 5 Must-Know Reactions of Benzene and 3 Must-Know Reactions of MethylBenzene.

Must-Know Benzene Reaction

1. Nitration of benzene to form nitrobenzene using concentrated HNO3 in concentrated H2SO4 at 50 to 60 degree celsius

4. Friedel-Crafts Alkylation of benzene to form alkylbenzene using chloroalkane in AlCl3 catalyst

5. Friedel-Crafts Acylation of benzene to form acylbenzene using acid chloride in AlCl3 catalyst

Must-Know Methylbenzene Reaction

1. Nitration of methylbenzene to form 2-nitromethylbenzene and 4-nitromethylbenzene using concentrated HNO3 in concentrated H2SO4 at 30 degree celsius

2. Halogenation (Chlorination) of methylbenzene to form 2-choloromethylbenzene and 4-chloromethylbenzene using chlorine in AlCl3 catalyst

3. Oxidation of alkyl side chain using KMnO4 in dilute H2SO4, heat or reflux to form benzoic acid

Memorising the reagents and conditions for these benzene reactions is an integral part of Organic Chemistry, so I've added 2 short memory tests.

Let's see if you can remember all of them!
