Vedclass · Answer

(C) The reaction of $but-1-yne$ $(CH_3-CH_2-C \equiv CH)$ with cold alkaline $KMnO_4$ (Baeyer's reagent) leads to the oxidative cleavage of the triple bond. Since the terminal carbon is involved,it is oxidized to $CO_2$ and $H_2O$,while the remaining part forms a carboxylic acid. The reaction is: $CH_3-CH_2-C \equiv CH \xrightarrow{	ext{Cold alk. } KMnO_4} CH_3CH_2COOH + CO_2$.

$But-1-yne$ reacts with cold alkaline $KMnO_4$ to produce:
