Question 1

Addition

Answer 1

An addition reaction is a reaction in which an atom or molecule is added to an unsaturated molecule, making a single product

Question 2

Hydrolysis

Answer 2

Hydrolysis is the reverse of condensation. “Hydro” indicates that water is involved and “lysis” means to break apart. In a hydrolysis reaction, water is added and the molecule breaks apart, usually at a C−O−C C−O−C linkage.

Question 3

Condensation

Answer 3

A condensation reaction is a reaction in which two molecules combine to form a single molecule. A small molecule, often water, is usually removed during a condensation reaction

Question 4

Elimination

Answer 4

An elimination reaction involves the removal of adjacent atoms from a molecule. This results in the formation of a multiple bond and the release of a small molecule, so they are called elimination reactions. They have the general form

Question 5

Substitution reaction

Answer 5

A substitution reaction, which is the same as a single replacement reaction in inorganic reactions, is a reaction in which one or more atoms in a molecule are replaced with another atom or group of atoms.
