==Key Stage 4==
===Meaning===
A '''general formula''' is a way to represent the the [[ratio]] of [[atom]]s in a [[Homologous Series|homologous series]].
===About General Fromulae===
: '''General formulae''' allow [[Chemist]]s to predict the number of one type of [[atom]] in a [[compound]] using the number of another [[atom]].
The '''general formulae''' you should know:
*[[Alkane]]s - C<sub>n</sub>H<sub>2n+2</sub>
*[[Alkene]]s - C<sub>n</sub>H<sub>2n</sub>
*[[Alcohol]]s - C<sub>n</sub>H<sub>2n+2</sub>O
*[[Carboxylic Acid]]s - C<sub>n</sub>H<sub>2n</sub>O<sub>2</sub>
