Question

Formaldehyde cannot undergo aldol condensation as well as Cannizzaro’s reaction.

(a) Trues

(b) False

This question was posed to me in examination.

My question is taken from Aldehydes and Ketones Chemical Reactions topic in portion Aldehydes, Ketones and Carboxylic Acids of Chemistry – Class 12

Answer 1

Right option is (b) False

To elaborate: Formaldehyde (HCHO) does not contain an α-hydrogen and hence cannot undergo self-condensation to form aldol product. However, it undergoes Cannizzaro’s reaction to given methanol and potassium formate.
