Benzene can undergo

Explain, why does benzene not undergo addition reactions easily?

Benzene undergo desulphonation but not denitration. Why ?

Assertion (A) Friedel - Crafts reaction benzene with n - propyl chloride on heating produce isopropyl benzene Reason (R ) Benzene undergoes electrophilic substitution easily.

(A) : Benzene reacts with n-propyl chloride in presence of AlCl_(3) to give isopropyl benzene. (R ) : Benzene undergoes electrophilic substitution readily.

Assertion (A) Friedel - Crafts reaction benzene with n - propyl chloride on heating produce isopropyl benzene Reason (R ) Benzene undergoes electrophilic substitution easily.

Explain why benzene mainly undergoes electrophilic substitution reaction ?

Benzene undergoes substituion reaction more easily than addition because
