Question

What is the product formed in the reaction of benzaldehyde with formaldehyde heating in aqueous NaOH.

Answer 1

This reaction is called Cross Cannizzaro reaction .
In this reaction conc.NaOH is uesd .
benzaldehyde (C6H5CHO) + Formaldehyde (HCHO) ==》 Benzyl alcohol (C6H5CH2OH) + Formic acid (HCOOH).
I hope it will help u...

Answer 2

Answer: The product formed will be benzyl alcohol and sodium methanoate.

Explanation:

The reaction between benzaldehyde and formaldehyde is an example of Crossed Cannizzaro's reaction where formaldehyde is oxidized and benzaldehyde is reduced.

Cannizzaro's reaction happens when aldehydes do not contain $\alpha$-hydrogen and under alkanline conditions undergo intermolecular oxidation and reduction to form alcohol and a salt of aromatic carboxylic acid as the final products.

The product for the reaction of benzaldehyde and formaldehyde will yield benzyl alcohol and sodium methanoate.

The reaction is given below.
