Show how will you synthesie:
i. 1-Phenylethanol form a suitable alkene.
ii. Cyclohexylmethanol using an alkyl halide by `SN^(2)` reaction.
iii. Pentan-1-ol using a suitable alkyl halide.

Explanation

i. Addition of `H_(2)O~ to ethenylbenzene in the pressence of dil. `H_(2)SO_(4)` gives 1-phenylethanol.

ii. Hydrolysis of cyclohexylmethyl bromide by aqueous NaOH gives cyclohexylmethanol.

iii. Hydrolysis of 1-bromopropane by aqueous NaOH gives propan-1-ol.
