What is displayed formulae

They show every atom and every bond seperately

What is structural formulae

It shows (unambiguously) how the atoms are joined together

What is skeletal formula

A zigzag line that shows only the bonds between the carbon atoms

What is molecular formulae

It shows the actual number of each atom in a molecule

What is empirical formulae

It shows the numbers of each atom in the simplest whole-number ratio

What is a functional groups

An atom or group of atoms that gives the compound distinctive and predictable properties

What is a homologous series

A set of compounds with the same functional group, similar chemical properties and physical properties that show a gradation

What is the priority list for locant numbers

1) Carboxylic acids

2) Aldehydes

3) Ketones

4) Alcohols

5) Alkenes

6) Alkanes

What is a hazard?

Something that can cause harm due to the inherent properties of the substance

What is a risk?

The chance that a hazard will actually happen
