Why aldehyde and ketone undergo nucleophilic addition reaction?
Due to greater electronegativity of oxygen than carbon, the C atom of the C=O. group acquires a partial positive charge in aldehydes and ketones and hence readily undergo nucleophilic addition reactions.Why aldehydes and ketones undergo nucleophilic addition while alkenes undergo electrophilic addition?
Answer: Alkenes undergo electrophilic addition, whereas aldehydes and ketones undergo nucleophilic addition because, in alkenes, the double bond joins two carbon atoms, and there is no resultant polarity. While in carbonyl compounds, the double bond joins atoms having different polarities.Does aldehydes and ketones undergo addition reaction?
Aldehydes and ketones undergo nucleophilic addition reactions, which is a reaction that occurs since the oxygen atom now has a negative charge, it can pick up a hydrogen ion from solution, forming alcohol on the carbonyl carbon.- Because the carbonyl carbon of aldehydes and ketones do not contain suitable leaving groups, their primary reaction is fundamentally different than carboxylic acid derivatives. Remember that aldehydes and ketones tend to undergo nucleophilic addition to form a tetrahedral alkoxide intermediate.
