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.
2,2-Dimethylbutanal.

Explanation

2-dimethylbutanal do not contain `alpha`-hydrogen. Hence, these undergo Cannizzaro.s reaction. The reactions and the structures of the expected products are given below :
`underset("2-2-Dimethylbutanal")( CH_(3)CH_(2)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)C-CHO)overset("Conc. NaOH")tounderset("2,2-Dimethylbutanal-1-ol")(CH_(3)CH_(2)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)C-CH_(2)OH)+underset("Sod. 2, 2-dimethylbutanoate")(CH_(3)CH_(2)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)C-COONa)`
