A general formula is a way to represent the the ratio of atoms in a homologous series.
About General Fromulae
- General formulae allow Chemists to predict the number of one type of atom in a compound using the number of another atom.
The general formulae you should know:
- Alkanes - CnH2n+2
- Alkenes - CnH2n
- Alcohols - CnH2n+2O
- Carboxylic Acids - CnH2nO2
