Show how will you synthesise:
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) `{:(C_(6)H_(5)-CH=CH_(2)+H_(2)O overset([H^(+)])(rarr)C_(6)H_(5)-CH-CH_(3)),(" |"),(" "OH),(" Styrene"" 1-phenylethanol"):}`
(ii)
(iii) `underset("1-Bromopentane")(CH_(3)CH_(2)CH_(2)CH_(2)CH_(2)Br)+KOH (aq) rarr underset("Penran-1-ol")(CH_(3)CH_(2)CH_(2)CH_(2)CH_(2)OH)+KBr`
