(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?

Answer 1

Synthesis of 1-pentanol using a suitable alkyl halide : When 1-Bromo pentane reacts with aq. KOH to form 1-pentanol.
`underset(1-"Bromo pentane")(overset(5)CH_(3)-overset(4)CH_(2)-overset(3)CH_(2)-overset(2)CH_(2)-overset(1)CH_(2)-Br)+ aq.KOH to underset(1-"Pentanol")(CH_(3)-CH_(2)-CH_(2)-CH_(2)-CH_(2)-OH+KBr)`
