I got this objective question which asks for the product obtained from chlorination of toluene in presence of light & heat, followed by treatment with aq.NaOH
D) benzoic acid
I think the presence of light would lead to chlorination under free radical mechanism..resulting in substitution of all hydrogens on the benzene ring by chlorine,but that leads to nowhere, i mean what will happen on treatment with aq.NaOH then?
Further since this was an objective ques, i already know the answer which is Benzoic Acid but I am unable to conclude a plausible mechanism.
Thanks in advance!
