Question
Prepare chart of hydrocarbons and note down the characteristics.

Answer
Characteristics of hydrocarbons:
- They are chemical compounds that are formed from only hydrogen and carbon atoms.
- Both ‘C’ and ‘H’ share an electron pair forming covalent bonds.
- One of the special properties of carbon is its ability to form double and triple bonds (unsaturation). Saturated hydrocarbons are alkanes and cycloalkanes while the unsaturated hydrocarbons are the aromatics, alkenes and alkynes.
- All hydrocarbons are insoluble in water, their boiling point increases as the size of alkane increases.
- All hydrocarbons can reach complete oxidation.
- Hydrocarbons are mainly used as fuel for transport and industry.
[Note: Students are expected to collect additional information on hydrocarbons on their own.]
