Reaction of benzene with a mixture of co...

Reaction of benzene with a mixture of conc.`HNO_(3)` and Conc`H_(2)SO_(4)` at about `60^(@)C` give nitrobenzene. Nitration of substituted benzenes depends on the nature of the group already present in the ring. Increase of temperature may result in multiple nitration.
Which of the following compounds undergo nitration at a rate faster than the other

A

Toluene

B

Phenol

C

Benzene

D

Chlorobenzene

Text Solution

    Electrophilic substitutions are characteristic reaction of aromatic compounds. In this reaction hydrogen of the aromatic ring is replaced by an electophile because hydrogen in the form of HR is very good leaving group. -COOH and -SO_3H are also good leaving groups when they are present either at ortho or at para to the highly activating groups like -NH_2 and -OH. Which one of the following compounds will be most unreactive towards electrophilic substitution reaction?

    The nitro group is a very strong deactivating group Nitro benzene undergoes nitration at a rate only 10-4 times that of benzene. The nitro group is a meta-directing group. When nitrobenzene is nitrated with nitration mixture 93% of meta substituted product is formed. Ring deactivating groups are :
