Vedclass · Answer

(C) The reaction involves the acid-catalyzed dehydration of a primary alcohol,$2$-cyclohexylethanol. Step $1$: Protonation of the hydroxyl group to form a good leaving group,$-OH_2^+$. Step $2$: Loss of water molecule to form a primary carbocation,$C_6H_{11}-CH_2-CH_2^+$. Step $3$: The primary carbocation undergoes a $1,2$-hydride shift to form a more stable secondary carbocation,$C_6H_{11}^+-CH_2-CH_3$. Step $4$: Elimination of a proton from the adjacent carbon leads to the formation of the most stable alkene,which is the more substituted alkene,$1$-ethylcyclohexene.

Column-$I$ (Reagents)	Column-$II$ (Products)
$A$. $HCl + ZnCl_2$	$i$. $CH_3CH=CHCH_3$
$B$. $HBr$	$ii$. $CH_3CH_2CH_2CH_2Cl$
$C$. $SOCl_2$	$iii$. $CH_3CH_2CH_2CH_2Br$
$D$. $H_2SO_4, \Delta$	$iv$. $CH_3CH_2CH_2CH_2Cl$

The reaction of $2$-cyclohexylethanol with $H^{\oplus}$ and $\Delta$ yields a major product $A$. Identify $A$.
