Addition, Elimination, and Substitution Reactions (Grade 12 NSC Matric Physical Sciences): Flashcards

Two+ reactants combine to form a single product

Reactant breaks into two products

Exchange of elements in reactants

H adds to C with fewer C neighbours (least substituted)

Unsaturated compounds (with double/triple bonds)

Addition of H and halogen atom to $C=C$ bond

Alcohol (from adding $H_2O$ to alkene)

Heat (~70°C), strong base in ethanol

High temp (~180°C) with strong acid catalyst

Halogen replaced by OH to form alcohol
