Question

Among the following the reaction that proceeds through an and electrophilic substitution is :

Answer 1

Benzene reaction with chlorine in presence of Aluminium chloride to form chloro benzene is an electrophilic substitution reaction.

Explanation:

An electrophilic substitution reaction is a reaction in which an electrophile is a reaction agent and it is substituted in the main reactant to form product.

In given reactions, the electrophilic substitution reaction is

Answer 2

The raction in option two, i.e. the reaction of benzene and chlorine in the presence of aluminium chloride proceeds through an electrophilic substitution.

• The first reaction is an example of eleimination of nitrogen followed by addition of chlorine.
• The second reaction is the electrophilic aromatic substitution of chlorine on benzene (since H+ is replaced by a Cl+).
• The third reacction is free radical addition reaction as it takes place in presence of light.
• The fouth reaction is an example of nucleophilic substitution of hydroxyl group by chloride group.
