Question

The hydrocarbon which does not decolourise alkaline KMnO4 solution and also does not give any precipitate with ammonia Cal silver nitrate is (A) acetylene (B) benzene (C) propyne (D) butyne-1

Tardigrade Admin · Accepted Answer

Benzene is resonance stabilized and hence, does not react with alkaline KMnO4 and it has no acidic hydrogen. Therefore, it does not react with ammoniacal silver nitrate solution.
