Vedclass · Answer

(C) $1$. The compound must react with $[Ag(NH_3)_2]^+$ (Tollens' reagent),which indicates it is a terminal alkyne $(R-C \equiv CH)$.$2$. Upon oxidation with alkaline $KMnO_4$,a terminal alkyne undergoes oxidative cleavage of the triple bond to form a carboxylic acid $(R-COOH)$ and $CO_2$.$3$. The product given is $(CH_3)_3C-COOH$ (pivalic acid). This implies the starting terminal alkyne must be $(CH_3)_3C-C \equiv CH$.$4$. The reaction is: $(CH_3)_3C-C \equiv CH + [O] \xrightarrow{alkaline \ KMnO_4} (CH_3)_3C-COOH + CO_2$.

Which of the following compounds reacts with $[Ag(NH_3)_2]^+$ and gives $(CH_3)_3C-COOH$ upon oxidation with alkaline $KMnO_4$?
