Question
Give any two differences between alkanes and alkenes.
Solution
Differences between alkanes and alkenes:
| Alkanes | Alkenes |
| Alkanes are saturated hydrocarbons in which the carbon atoms are linked to each other only by single covalent bonds. | Alkenes are unsaturated hydrocarbons in which the valencies of carbon atoms are not fully satisfied by single covalent bonds. |
| They contain only a single bond. | They contain triple bonds. |
| They are chemically less reactive. | They are chemically more reactive. |
| The substitution reaction is a characteristic property of alkanes. | The addition reaction is a characteristic property of alkenes |
| Their general formula is CnH2n + 2. | Their general formula is CnH2n |
