Vedclass · Answer

(D) Monochlorination of methylcyclohexane $(C_7H_{14})$ occurs at different positions:$1$. At the methyl group: $1$ isomer (chloromethylcyclohexane).$2$. At the $C_1$ position: $1$ isomer ($1$-chloro$-1-$methylcyclohexane).$3$. At the $C_2$ position: $2$ chiral centers are present,leading to $2^2 = 4$ stereoisomers.$4$. At the $C_3$ position: $2$ chiral centers are present,leading to $2^2 = 4$ stereoisomers.$5$. At the $C_4$ position: $2$ stereoisomers (cis and trans$-1-$chloro$-4-$methylcyclohexane).Total isomers = $1 + 1 + 4 + 4 + 2 = 12$.

List-$I$	List-$II$
$A$. The reaction of $1,6$-dibromohexane with $Zn$.	$i$. $H_3C-C \equiv CH$
$B$. Reaction of ethanol with concentrated $H_2SO_4$ at $443 \ K$.	$ii$. $H_2C=CH_2$
$C$. Major product in the reaction of propene with $HBr$ in the presence of benzoyl peroxide.	$iii$. $CH_3-CH_2-CH_2-Br$
$D$. The reaction of $1,1$-dibromopropane with $NaNH_2$ at $433 \ K$.	$iv$. Cyclohexane

Total number of isomers (including stereoisomers) obtained on monochlorination of methylcyclohexane is $........$
