Monochlorination of toluene in sunlight followed by hydrolysis with aq. NaOH yields
(a) o - cresol
(b) m - cresol
(c) 2, 4 - dihydroxytoluene
9d) benzyl alcohol
Monochlorination of toluene in sunlight gives benzyl chloride. On hydrolysis with aq. NaOH, benzyl chloride shows nucleophilic substitution reaction to give benzyl alcohol.
So, the correct option is (d).
