Which of the following compounds will undergo aldol condensation, which the Cannizzaro reaction and which neither ? Write the structures of the expected products of aldol condensation and Cannizzaro reaction.
Methanal

Explanation

Methanal do not contain `alpha`-hydrogen. Hence, these undergo Cannizzaro.s reaction. The reactions and the structures of the expected products are given below :
`underset("Methanal")( 2HCHO)overset("Conc. "NAOH)tounderset("Methanol")(CH_(3)OH)+underset("Sod. methanoate")( HCOONa)`
