Chlorination of toluene in presence of light and heat followed by treatment with aqueous $NaOH$ gives

detailed solution

Correct option is D

Given data : It is given to identify the  chlorination of toluene in presence of light and heat followed by treatment with aqueous $NaOH$ gives

Explanation

Toluene is a transparent, colorless liquid that, when heated to room temperature, turns into a vapor. A strong or sweet smell coming from toluene vapor indicates exposure. Typically, toluene is combined with other solvents, chemicals, and substances like paint pigments.

Toulene is chlorinated in the presence of light and heat, and then the chemical is treated with aqueous NaOH to produce benzoic acid. 

Hence the correct option (D).Benzoic acid
