Question
Alkane and Alkene.

Answer

Alkane
1. Alkanes in which the carbon atoms are linked to each other only by single bonds.
2. The general formula of an alkane is $\mathrm{C}_n \mathrm{H}_{2 n+2}$
3. They are chemically less reactive.
Alkene:
1. Alkenes in which carbon atoms are linked to each other by double bonds.
2. The general formula of an alkene is $\mathrm{C}_n \mathrm{H}_{2 n}$.
3. They are chemically more reactive.
