Show how will you synthesise:
(i) 1-phenylethanol from a suitable alkene.
(ii) cyclohexylmethanol using an alkyl halide by an `S_(N)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.
