Identify (X), (Y) and (Z) in the given reaction.
\(\mathrm{CH}_{3} \mathrm{CHO} \xrightarrow[\mathrm{H}_{2} \mathrm{SO}_{4}]{\mathrm{K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7}}(X) \xrightarrow{\mathrm{PCl}_{5}}(Y) \xrightarrow[\text { anh. } \mathrm{AlCl}_{3}]{\mathrm{C}_{6} \mathrm{H}_{6}}(Z)\)
\(\mathrm{CH}_{3} \mathrm{CHO} \xrightarrow[\mathrm{H}_{2} \mathrm{SO}_{4}]{\mathrm{K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7}}(X) \xrightarrow{\mathrm{PCl}_{5}}(Y) \xrightarrow[\text { anh. } \mathrm{AlCl}_{3}]{\mathrm{C}_{6} \mathrm{H}_{6}}(Z)\)
- (X) = HCOOH, (Y) = COCl2, (Z) = C6H5Cl
- (X) = CH3COOH, (Y) = CH3COCl, (Z) = C6H5COCH3
- (X) = CH3COOH, (Y) = CH3CH2CH2Cl, (Z) = C6H5CH2CH2CH3
- (X) = CH3COCH3, (Y) = CH3CHClCH3, (Z) = C6H5COCH3
Answer
(B) ( X ) = CH 3 COOH, ( Y ) = CH 3 COCl, ( Z ) = C 6 H 5 COCH 3
