Vedclass · Answer

(B) Ozonolysis of an internal alkyne $(R-C \equiv C-R')$ followed by hydrolysis yields carboxylic acids $(RCOOH + R'COOH)$.For the product to be only butanoic acid $(CH_3CH_2CH_2COOH)$,the alkyne must be symmetrical with a four-carbon chain on each side of the triple bond.Thus,the alkyne is $CH_3CH_2CH_2-C \equiv C-CH_2CH_2CH_3$,which is $4-$octyne.Reaction: $CH_3CH_2CH_2-C \equiv C-CH_2CH_2CH_3 \xrightarrow{O_3, H_2O} 2CH_3CH_2CH_2COOH$.

Which alkyne yields butanoic acid $(CH_3CH_2CH_2CO_2H)$ as the only organic product on treatment with ozone followed by the hydrolysis?
