Some hydrocarbons are regarded as unsaturated because they contain double or triple bonds between adjacent carbon atoms.
<h3>What are hydrocarbons?</h3>
Hydrocarbons are any organic compounds that contain hydrogen and carbon in its structure.
Hydrocarbons can be grouped into the following based on whether they contain single or double bonds:
- Saturated hydrocarbons - contain only single bonds e.g. alkanes
- Unsaturated hydrocarbons - contain double and triple bonds e.g. alkenes
Therefore, it can be said that some hydrocarbons are regarded as unsaturated because they contain double or triple bonds between adjacent carbon atoms.

Oxygen, fluorine and iodine are diatomic elements. Flourine is more reactive than the other two because it is the closest away to filling its outer layer of electrons and becoming stable like a noble gas.
