Vedclass · Answer

(B, D) $X$ is Benzaldehyde $(Ph-CHO)$ because it gives a positive Tollen's test but a negative Fehling test.The reaction of Benzaldehyde with acetic anhydride in the presence of sodium acetate is the Perkin reaction,which produces Cinnamic acid $(Y)$: $Ph-CHO + (CH_3CO)_2O \xrightarrow{CH_3COONa} Ph-CH=CH-COOH$ $(Y)$.Then,$Ph-CH=CH-COOH$ $\xrightarrow{SOCl_2} Ph-CH=CH-COCl$ $\xrightarrow{Me_2NH} Ph-CH=CH-CON(CH_3)_2$ $(Z)$.Thus,options $B$ and $D$ are correct.

$C_7H_6O$ is the molecular formula of $X$,which gives a negative Fehling test but a positive Tollen's test. $X$ $\xrightarrow[AcONa]{Ac_2O} Y$ $\xrightarrow[Me_2NH]{1. SOCl_2} Z$. The correct option is:
