Vedclass · Answer

(C) $1$. Identify the products $x, y, z$:- Reaction $1$: Cyclohexene + $HBr$ gives bromocyclohexane $(x)$.- Reaction $2$: $1-$methylcyclohexene + $HCl$ gives $1-$chloro$-1-$methylcyclohexane $(y)$.- Reaction $3$: Cyclohexanol + $SOCl_2$ gives chlorocyclohexane $(z)$.$2$. Analyze $S_{N}1$ reactivity:- $S_{N}1$ reactivity depends on the stability of the carbocation intermediate formed.- $y$ is $1-$chloro$-1-$methylcyclohexane (tertiary alkyl halide),which forms a stable tertiary carbocation.- $x$ is bromocyclohexane (secondary alkyl halide),which forms a secondary carbocation.- $z$ is chlorocyclohexane (secondary alkyl halide),which forms a secondary carbocation.- Comparing $x$ and $z$: The leaving group ability of $Br^-$ is better than $Cl^-$,making $x$ more reactive than $z$.$3$. Order of reactivity: $y$ (tertiary) > $x$ (secondary,$Br$) > $z$ (secondary,$Cl$).Therefore,the correct order is $y > x > z$.

Observe the following reactions. The order of reactivity of $x, y, z$ towards $S_{N}1$ reaction is:
