Question

48. Thiols are formed by reducing the dialkyl disulphides with
(A) zinc
(B) acid
(C) both zinc and acid
(D) none of these​

Answer 1

Answer:

Thiols can be made from haloalkanes by nucleophilic substitution of the halide ion by the sulfhydryl ion (HS−), which is an excellent nucleophile. Because thiolate ions are also excellent nucleophiles, thioethers can react again to give a thioether.

Answer 2

(B) Acid is the solution....
