Vedclass · Answer

(C) The $2,4-DNP$ ($2$,$4$-dinitrophenylhydrazine) test is a characteristic chemical test used to identify the presence of a carbonyl group,specifically in aldehydes and ketones.$1$. Acetic acid is a carboxylic acid and does not give the $2,4-DNP$ test.$2$. $1$-Butyne is an alkyne and does not give the $2,4-DNP$ test.$3$. Butan$-2-$one is a ketone,which contains a carbonyl group $(>C=O)$,and therefore it reacts with $2,4-DNP$ to form a yellow or orange precipitate.$4$. Butan$-2-$ol is an alcohol and does not give the $2,4-DNP$ test.Thus,the correct compound is Butan$-2-$one.
