ORGANIC MECHANISMS MENU

Free radical reactions . . .

Free radical substitution reactions in alkanes and alkyl groups. Free radical addition during the polymerisation of ethene and the reaction between HBr and alkenes in the presence of organic peroxides.

Electrophilic addition reactions . . .

Addition reactions of alkenes such as ethene and propene.

Electrophilic substitution reactions . . .

Substitution reactions of benzene and other simple arenes.

Nucleophilic substitution reactions . . .

Substitution reactions of halogenoalkanes such as bromoethane.

Elimination reactions . . .

The formation of alkenes from halogenoalkanes such as 2-bromopropane, and from the dehydration of alcohols.

Nucleophilic addition reactions . . .

Addition reactions of carbonyl compounds such as ethanal and propanone.

Nucleophilic addition / elimination reactions . . .

The reactions of acyl chlorides (acid chlorides) with water, alcohols, ammonia and amines.
