Vedclass · Answer

(D) $2,4-$dinitrophenylhydrazine $(2,4-DNP)$ is a reagent used to detect carbonyl groups (aldehydes and ketones). Since the compound does not react with $2,4-DNP$,it is not an aldehyde or a ketone. $Na$ metal reacts with compounds containing active hydrogen atoms,such as alcohols $(R-OH)$. Since the compound does not react with $Na$,it does not contain an active hydrogen atom (i.e.,it is not an alcohol). Among the options: $A$) Acetone is a ketone. $B$) Acetaldehyde is an aldehyde. $C$) $CH_3OH$ is an alcohol. $D$) $CH_3OCH_3$ (dimethyl ether) is an ether,which does not contain a carbonyl group nor an active hydrogen atom. Therefore,it does not react with $2,4-DNP$ or $Na$.

$A$ compound does not react with $2,4-$dinitrophenylhydrazine and $Na$. The compound is:
