Alkanes for Edexcel GCSE Chemistry
This page covers the following topics:
1. Formulae and solubility of alkanes
2. First four alkanes
3. Molecular formula of alkanes
Alkanes are saturated hydrocarbons, they are non-polar so are insoluble in water.
The first 4 alkanes follow the usual naming pattern for hydrocarbons.
Molecular formula shows the number and type of atoms present in a molecule, remember that for alkanes they will follow the general formula from before.
How does solubility of alkanes change with chain length?
Shorter alkanes are slightly more soluble than longer chain alkanes.
What is the name of the molecule C₂H₆?
What is the general formula of alkanes?
What is the molecular formula of ethane?
What is the molecular formula for an alkane with 20 carbon atoms?
