Question

1-Butyne on oxidation with hot alkaline KMnO4 would yield

Answer 1

on oxidation with kMnO4 with 1,butyne gives carboxylic acid

Answer 2

Explanation:

When terminal alkynes are treated with hot alkaline potassium permanganate they give out carbon-dioxide gas and carboxylic acid. This reaction is known as oxidation of alkynes.

$R-C\equiv C^*H+KMnO_4\rightarrow R-COOH+C^*O_2$

When 1-butyne on oxidation by $KMnO_4$ will giev propanoic acid and carbondioxide gas.
