(A) The reaction sequence is as follows:$1$. $CH_3-CH_2-COOH + PCl_3 ightarrow CH_3-CH_2-COCl$ (Compound $I$,Propanoyl chloride).$2$. $CH_3-CH_2-COCl + C_6H_6 \xrightarrow{AlCl_3} C_6H_5-CO-CH_2-CH_3$ (Compound $II$,Propiophenone,which is also known as ethyl phenyl ketone).$3$. $C_6H_5-CO-CH_2-CH_3 \xrightarrow{NH_2-NH_2/	ext{base/heat}} C_6H_5-CH_2-CH_2-CH_3$ (Compound $III$,Propylbenzene).This is a Friedel-Crafts acylation followed by a Wolff-Kishner reduction.

The final product $(III)$ obtained in the reaction sequence is:
$CH_3-CH_2-COOH$ $\xrightarrow{PCl_3} I$ $\xrightarrow{C_6H_6/AlCl_3} II$ $\xrightarrow{NH_2-NH_2/\text{base/heat}} III$
