Question

Steps involved in formation of adiponitrile are _______

(a) Benzene → adipic acid → cyclohexane → adiponitrile

(b) Cyclohexane → benzene → adipic acid → adiponitrile

(c) Benzene → cyclohexane →adipic acid → adiponitrile

(d) Cyclohexane → adipic acid → benzene → adiponitrile

This question was addressed to me in examination.

My enquiry is from Inorganic Chemical in chapter Inorganic Chemical Industries of Chemical Technology

Answer 1

Correct option is (c) Benzene → cyclohexane →adipic acid → adiponitrile

Easiest explanation: Benzene on reduction gives cyclohexane, which further t forming adipic acid. Adipic acid on dehydration in presence of ammonia forms an amide which on dehydration produces adiponitrile.
