Vedclass · Answer

(D) $1$. Cyclohexane reacts with $Br_2$ in the presence of $h
u$ (free radical substitution) to form bromocyclohexane $(A)$.$2$. Bromocyclohexane $(A)$ reacts with $Na$ in dry ether (Wurtz reaction) to form bicyclohexyl $(B)$.$3$. Bicyclohexyl $(B)$ reacts with $Br_2$ in the presence of $h
u$ to form $1-$bromobicyclohexyl $(C)$.$4$. $1-$bromobicyclohexyl $(C)$ undergoes hydrolysis with $H_2O$ to form $1-$hydroxybicyclohexyl (or $1-$cyclohexylcyclohexanol) $(D)$.$5$. $1-$cyclohexylcyclohexanol $(D)$ undergoes acid-catalyzed dehydration with $conc. H_2SO_4$ to form the major product $(E)$,which is bicyclohexylidene (or dicyclohexylidene).

Identify the major product $'E'$ in the following reaction sequence:
Cyclohexane $\xrightarrow{Br_2, h\nu} (A)$ $\xrightarrow{Na, D.E.} (B)$ $\xrightarrow{Br_2, h\nu} (C)$ $\xrightarrow{H_2O} (D)$ $\xrightarrow{conc. H_2SO_4} (E)$
