A mixture of benzaldehyde and formaldehyde on heating with aqueous NaOH solution gives:
Correct answer: A. benzyl alcohol + sodium formate
- A. benzyl alcohol + sodium formate
- B. sodium benzoate + methanol
- C. benzyl alcohol + methanol
- D. sodium benzoate + sodium formate
Explanation
When a mixture of benzaldehyde and formaldehyde is heated with aqueous NaOH (sodium hydroxide) solution, it undergoes a reaction known as the Cannizzaro reaction. In this reaction, one molecule of aldehyde is oxidized to its corresponding salt, while another molecule of aldehyde is reduced to an alcohol.The reaction between benzaldehyde and formaldehyde in the presence of NaOH leads to the formation of benzyl alcohol and sodium formate.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
