Reaction Types

What is an addition reaction?

Two molecules join to form one product (usually across a C=C bond)

What is an elimination reaction?

One molecule splits to form a double bond + small molecule (e.g. H2O or HX)

What is a substitution reaction?

One atom or group is replaced by another

What is a nucleophilic substitution?

A nucleophile replaces a leaving group (e.g. OH- replaces halogen)

What is an electrophilic addition?

An electrophile adds across a C=C double bond

What is an oxidation reaction?

Gain of oxygen OR loss of hydrogen

What is a reduction reaction?

Gain of hydrogen OR loss of oxygen

What is a condensation reaction?

Two molecules join and produce to form a larger molecule and a small molecule (usually water)

What is a hydrolysis reaction?

A molecule is broken using water

What is a neutralisation reaction?

Acid reacts with base to form salt + water
