Solution

(i) Hydrolysis of cyclohexyl methyl bromide by aqueous $N a O H$ gives cyclohexyl methanol.
ii) $C H_{3} C H_{2} C H_{2} C H_{2} C H_{2} C l + N a O H \to C H_{3} C H_{2} C H_{2} C H_{2} C H_{2} O H + N a C l$
1-Chloropentane Pentan-1-ol
(iii) $C_{6} H_{5} - C H = C H_{2} + H_{2} O H^{+} - - \to C_{6} H_{5} C H (O H) C H_{3}$
1-Phenylethanol
