(i) 1-phenylethanol from a suitable alkene.
(ii) cyclohexylmethanol using an alkyl halide by an SN2 reaction.
(iii) pentan-1-ol using a suitable alkyl halide?

(i)

1 – phenylethanol can be made by acid-catalyzed hydration of ethylbenzene ( styrene).

(ii) Cyclohexyl methanol is produced by treating chloromethyl cyclohexane with sodium hydroxide.

(iii) When 1 – chloropentane is treated with NaOH, pentan – 1 – ol is produced.
