The alkynes are less reactive than alkynes towards halogens toon. Why?

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.

How can explain that Chloral hydrate is stable Compound although it has two -OH groups attached to same carbon?

Chloral hydrate (CH3-CHO.2H2O) has unusual stability due to -I effect of three Chlorine atoms, which leads to the formation of two Hydrogen bond. The energy released in the formation of three bonds provides extra stability.
