When m-chlorobenzaldehyde reacts with a 50% KOH solution, it results in the formation of potassium meta chloro benzoate and meta chloro benzyl alcohol as the products.
It's important to note that in this reaction, there are no alpha hydrogen atoms present in m-chloro benzaldehyde. Consequently, the reaction follows a Cannizzaro reaction mechanism, where one molecule undergoes oxidation to form meta chloro benzoic acid, while another molecule undergoes reduction to produce meta chloro benzyl alcohol.
