(i) Write the differences between saturated and unsaturated hydrocarbons.
(ii) Write the molecular formula and structural formula of an alkene having five carbon atoms.

Explanation

Saturated hydrocarbons:
In carbon compounds, carbon atoms are satisfied by a single bond between them.
These compounds are normally not very reactive.
Unsaturated hydrocarbens:
In carbon ocmpounds, carbon atoms have double or triple bonds bctween them.
They are more reactive than the saturated carbon compounds.
