Vedclass · Answer

(A) The reaction sequence is as follows:$1$. Hydrolysis of $C_4 H_9 Br$ $(X)$ gives an alcohol $Y$ $(C_4 H_9 OH)$.$2$. The alcohol $Y$ undergoes dehydration with $20 \% H_3 PO_4$ at $358 \ K$ to form an alkene.$3$. Tertiary butyl bromide,$(CH_3)_3 CBr$,on hydrolysis gives tertiary butyl alcohol,$(CH_3)_3 COH$.$4$. Tertiary butyl alcohol undergoes easy dehydration with $20 \% H_3 PO_4$ at $358 \ K$ to form isobutylene ($2$-methylpropene),which is consistent with the provided reaction conditions.$5$. Therefore,$X$ is $(CH_3)_3 CBr$.

$A$ halogen compound $X$ $(C_4 H_9 Br)$ on hydrolysis gives an alcohol $Y$. The alcohol $Y$ undergoes dehydration with $20 \% H_3 PO_4$ at $358 \ K$. What is $X$?
