Arrange the following in the order of their increasing order of expected enol content. H3C-CO-CH2-CHO, H3C-CO-CH3, H3C-CHO and H3C-CO-CH2-CO-CH3 .

As the substituents at the enolic double bond in the enol increases, the enolic content increases.

Dimethyl acetaldehyde undergoes Cannizzaro's reaction despite its contains alpha hydrogen. explain.

Because of the presence of only one alpha hydrogen , it's alpha hydrogen is very very weak acidic and so aldol condensation is slower than Cannizzaro's reaction.
