JEE Main Chemistry question
A mixture of benzaldehyde and formaldehyde on heating with aqueous NaOH solution gives
Answer: (B)
Solution
Both benzaldehyde and formaldehyde lack α-hydrogens, so together they undergo a crossed Cannizzaro reaction. Formaldehyde, being more electrophilic (smaller, less hindered carbonyl) and thus the better hydride acceptor, is reduced to methanol while benzaldehyde is oxidized to benzoate —
