Vedclass · Answer

(A) In step $(i)$,benzoyl chloride undergoes reduction in the presence of $H_2, Pd / BaSO_4$ to give benzaldehyde.This reaction is known as the Rosenmund reduction. The reagent is a selective reducing agent,which reduces acid chlorides to an aldehyde group.In step $(ii)$,benzaldehyde undergoes condensation with acetic anhydride in the presence of an alkali salt of the acid $(NaOAc)$ to give cinnamic acid $(\alpha, \beta$-unsaturated aromatic acid).This reaction is known as the Perkin reaction.

In the reaction,
$C_6H_5COCl \xrightarrow[(ii) Y]{(i) X} C_6H_5CH=CHCOOH$
$X$ and $Y$ are
