What is Addition Reaction?
An addition reaction is a chemical reaction in which two or more molecules combine to form a single larger molecule, with no atoms lost as byproducts. Addition reactions typically occur across multiple bonds (C=C, C=O, C≡C). Common types include electrophilic addition (e.g., HBr to alkenes), nucleophilic addition (e.g., to carbonyls), and radical addition.

Hydrogenation of alkenes and alkynes (margarine production from vegetable oils); halogenation reactions; polymerisation (addition polymers like polyethylene); synthesis of alcohols, halides, and other organic compounds
Depends on reagents used — HBr, Cl₂, and HCN are toxic or corrosive. Hydrogenation requires H₂ gas under pressure (explosive). Always use appropriate PPE and fume hoods. Follow specific hazard guidelines for each reagent.
