Show how you would synthesize the following alcohols from appropriate alkenes:
$(i)$ $1$-methylcyclohexanol
$(ii)$ $3$-methylhexan-$3$-ol
$(iii)$ pentan-$2$-ol
$(iv)$ $2$-cyclohexylbutan-$2$-ol

(N/A) The given alcohols can be synthesized by the acid-catalyzed hydration of appropriate alkenes,which follows Markovnikov's rule.
$(i)$ $1$-methylcyclohexene + $H_2O \xrightarrow{H^+} 1$-methylcyclohexanol
$(ii)$ $3$-methylhex-$2$-ene + $H_2O \xrightarrow{H^+} 3$-methylhexan-$3$-ol
$(iii)$ $pent-2-ene + H_2O \xrightarrow{H^+} pentan-2-ol$
$(iv)$ $2-cyclohexylbut-2-ene + H_2O \xrightarrow{H^+} 2-cyclohexylbutan-2-ol$
