Question

What will be the products when benzaldehyde is treated with $NaOD$ in $D_{2}O$ ?

• A. $C_6{H}_{5}C{H}_{2}OD$ and $C_6{H}_{5}COONa$
• B. $C_6{H}_{5}C{H}_{2}OD$ and $C_6{H}_{5}COOD$
• C. $C_6{H}_{5}CHDOD$ and $C_6{H}_{5}COONa$
• D. $C_6{H}_{5}COOCHD{C}_6{H}_5$

Answer 1

Answer: (A)

Benzaldehyde on treatment with $50\%$ aqueous or ethanolic alkali solution undergoes Cannizzaro reaction i.e., one molecule is oxidised and one is reduced
