- Hydrocarbons are compounds that are made up of carbon (C) and hydrogen (H) atoms only
The diagram shows examples of hydrocarbons; Ethanol is NOT a hydrocarbon as the molecule also contains an oxygen atom and is not solely made up of carbon and hydrogen
Remember to state that hydrocarbons are ‘only’ made up of C and H atoms.
- A functional group is an atom or a group of atoms in an organic molecule which determines the physical and chemical properties of the molecule
- Alkanes are the simple hydrocarbons with no functional group
- They are made up of carbon and hydrogen atoms bonded to each other with single covalent bonds
