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

Answer»

Solution :In alkenes, the double bond is formed between two carbon atoms. There is no polarity in the bond. Butit polarises molecules like `Cl_(2), HCl, H_(2)O` ETC., resulting it in the attachment of ELECTROPHILE to one of the carbon atoms.
In carbonyl compounds, the double bond is between C and O. Oxygen being electronegative than carbon, the latter attains a SLIGHT POSITIVE charge. This positive carbon attracts the nucleophile giving rise to nucleophilic addition reactions.
