$CH_2=CH-OCH_3$

Vedclass · Answer

(B) The molecular formula $C_3H_6O$ corresponds to the degree of unsaturation $1$. Since the compound does not react with $2,4-$dinitrophenylhydrazine $(2,4-DNP)$,it does not contain a carbonyl group (aldehyde or ketone). Since it does not react with sodium metal,it does not contain an active hydrogen atom (like in an alcohol or phenol). Among the given options,$CH_3COCH_3$ (acetone) and $CH_3CH_2CHO$ (propanal) are carbonyl compounds. $CH_2=CHCH_2OH$ is an alcohol. $CH_2=CH-OCH_3$ (methoxyethene) is an ether,which does not react with $2,4-DNP$ or sodium metal. Therefore,the correct compound is $CH_2=CH-OCH_3$.

An organic compound with the molecular formula $C_3H_6O$ does not give a precipitate with $2,4-$dinitrophenylhydrazine and does not react with sodium metal. What is this compound?
