Nucleophilic addition reactions are pivotal in organic chemistry, enabling the creation of complex molecules from simpler ones. These reactions involve a nucleophile attacking an electrophilic carbon, often in carbonyl groups found in aldehydes and ketones. Their reactivity is crucial for synthesizing pharmaceuticals, polymers, and biomolecules. The text also explores nucleophilic addition-elimination reactions and their industrial significance in producing drugs, rubbers, fragrances, and dyes.

Nucleophiles are electron-rich species that donate a pair of electrons, while electrophiles are electron-poor species with a partial positive charge
Intermediate Formation
Nucleophiles attack electrophilic carbons, creating an intermediate
Proton Transfer
A proton is transferred from the intermediate to a base, completing the reaction
Aldehydes and ketones are highly reactive towards nucleophilic addition due to their carbonyl functional groups
Nucleophilic addition-elimination reactions involve both the addition of a nucleophile and the elimination of a leaving group
