(A) The reaction sequence is as follows:$1$. $CH_3CH_2COOH \xrightarrow{PCl_3} CH_3CH_2COCl$ (Propionyl chloride,$I$)$2$. $CH_3CH_2COCl \xrightarrow[AlCl_3]{C_6H_6} C_6H_5COCH_2CH_3$ (Propiophenone,$II$)$3$. $C_6H_5COCH_2CH_3 \xrightarrow[base, heat]{NH_2NH_2} C_6H_5CH_2CH_2CH_3$ (Propylbenzene,$III$)This is a Wolff-Kishner reduction where the ketone group is reduced to a methylene group. The final product is propylbenzene.

The final product $(III)$ obtained in the reaction sequence:
$CH_3CH_2COOH$ $\xrightarrow{PCl_3} I$ $\xrightarrow[AlCl_3]{C_6H_6} II$ $\xrightarrow[base, heat]{NH_2NH_2} III$ is
