Question

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

Tardigrade Admin · Accepted Answer

Benzene is resonance stabilised and hence does not react with alk. KMnO 4 and it has no acidic hydrogen. Therefore, it does not react with ammoniacal AgNO 3 solution.

Q. The hydrocarbon which does decolourise alkaline $K M n O_{4}$ solution and also does not give any precipitate with ammoniacal silver nitrate is

benzene

acetylene

propyne

butyne-1

Benzene is resonance stabilised and hence does not react with alk. $K M n O_{4}$ and it has no acidic hydrogen. Therefore, it does not react with ammoniacal $A g N O_{3}$ solution.
