Halogen acids readily combine with alkenes to form addition products but fail to react with carbonyl compounds. Discuss

Addition of HCN to carbonyl compounds is

Discussion on Carbonyl Compound

Alkenes and carbonyl compounds both contain a pi bond but alkenes show electrophilic addition reactions whereas carbonyl compounds show nucleophilic addition reactions. Explain.

Carbonyl compounds when treated with sodium bisulphate solution then generally a crystalline sodium bisulphite addition product is formed but which of the following carbonyl compound does not forms crystalline addition product

Ethanal reacts with HCN and the addition product so obtained is hydrolyzed to form a new compound. This compound shows
