What does your textbook say about 12.5 Chemical properties of aldehydes and ketones?
A) Nucleophilic addition reactions This reaction is the most common reactions of aldehydes and ketones. The carbonyl carbon carries a small degree of positive charge. Nucleophile such as CN − can attack the carbonyl carbon and uses its lone pair to form a new carbon – nucleophile ' σ ' bond, at the same time two electrons from the carbon – oxygen double bond move to the most electronegative oxygen atom. This results in the formation of an alkoxide ion. In this process, the hybridisation of carbon changes from sp to sp .
