Defitions For Organic Chemistry

Question 1

Homologous Series

Answer 1

A family of compounds which have similar chemical properties because they have the same functional group. Each member of a homologous series differs from the next by a CH2 group

Question 2

Functional group

Answer 2

The atom/group of atoms involved in the chemical reactions of a molecule.

Question 3

Hydrocarbon

Answer 3

A compound made up of only hydrogen and carbon

Question 4

Saturated hydrocarbon

Answer 4

A hydrocarbon that contains only single C-C bonds (no C=C double bonds)

Question 5

Unsaturated hydrocarbon

Answer 5

Contains at least one double bond

Question 6

Structural isomer

Answer 6

They are molecules with the same molecular formula but different structural formulae

Question 7

Molecular formula

Answer 7

States the total number of each type of atom in the molecule. Atoms of the same type must be grouped together.

Question 8

Empirical formula

Answer 8

Gives the simplest whole number ratio of the different types of atom in the molecule
