Vedclass · Answer

(C) $1$. Hydroboration-oxidation of styrene gives $P$ ($2$-phenylethanol,$C_6H_5CH_2CH_2OH$).$2$. Oxidation of $P$ with $CrO_3/H_2SO_4$ gives phenylacetic acid $(C_6H_5CH_2COOH)$.$3$. $HVZ$ reaction $(Cl_2/Red \ P)$ on phenylacetic acid gives $Q$ ($2$-chloro$-2-$phenylacetic acid,$C_6H_5CHClCOOH$).$4$. $P$ $(C_6H_5CH_2CH_2OH)$ reacts with $SOCl_2$ to give $C_6H_5CH_2CH_2Cl$,followed by $NaCN$ to give $C_6H_5CH_2CH_2CN$,and hydrolysis gives $R$ ($3$-phenylpropanoic acid,$C_6H_5CH_2CH_2COOH$).$5$. Intramolecular Friedel-Crafts acylation of $R$ using $conc. \ H_2SO_4$ gives $S$ ($1$-indanone).

List-$I$ (Name of reaction)	List-$II$ (Reagent used)
$A$. Hell-Volhard-Zelinsky reaction	$I$. $NaOH + I_2$
$B$. Iodoform reaction	$II$. $(i) CrO_2Cl_2, CS_2; (ii) H_2O$
$C$. Etard reaction	$III$. $(i) Br_2 / \text{red phosphorus}; (ii) H_2O$
$D$. Gatterman-Koch reaction	$IV$. $CO, HCl, \text{anhyd. } AlCl_3$

Consider the following reaction scheme and choose the correct option for the major products $Q$,$R$ and $S$.
