Question

Alkenes (>C=C<) and carbonyl compounds (>C=0) , both contain a л-bond but alkenes show electrophilic addition reactions whereas carbonyl compounds show nucleophilic addition reactions. Explain.

Answer 1

Alkenes are electron rich species, because of that they generally show electrophilic addition reaction. While, In (>C=0) (Carbonyl). There is a electron deficiency at carbonyl carbon due to the presence of highly electronegative oxygen atom. Because of that carbonyls behave as a electrophilic and show nucleophilic addition reactions
