Question
Discuss the important addition reactions of benzene.
Solution
(i) The addition of hydrogen. Benzene reacts with hydrogen in the presence of a catalyst such as nickel or platinum at 473 to 573K under pressure to form cyclohexane.
(ii) The addition of halogens. Benzene reacts with chlorine or bromine in the presence of sunlight and absence of halogen carrier to form benzene hexachloride or benzene hexabromide.
BHC is used as an insecticide. It is sold under the name Gammexane or lindane.
(iii) The addition of ozone. Benzene reacts with ozone to form benzene tri ozonide.
