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.

Text Solution

Verified by Experts

(i) Addition of `H_(2)O` to ethenylbenzene is presence of dil `H_(2)SO_(4)`.

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

(iii) Hydrolysis of 1-bromopentane by aqueous NaOH gives pentan-1-ol.
