What are the main sources of alkanes and why they are known as saturated hydrocarbons?

उत्तर
The main sources of alkanes are natural gas and petroleum.
Alkanes are known as saturated hydrocarbons because the carbon atoms in their molecules are bonded to each other by single covalent bond. Each carbon atom is again bonded to hydrogen atom.
