Question

What is 'Hydrocarbons'? Explain saturated hydrocarbons and unsaturated hydrocarbons with examples.

Answer 1

Firstly hydrocarbons are defined as molecules only containing carbon and hydrogen, hence -hydro and -carbons. They are important for fuels, fragrances, detergents and many other things. An important member of the hydrocarbons are alkanes, alkenes, alkynes.

________________________________________________

✴ Unsaturated Hydrocarbons : Unsaturated hydrocarbons are hydrocarbons that have double or triple covalent bonds between adjacent carbon atoms. Those with at least one carbon-to-carbon double bond are called alkenes and those with at least one carbon-to-carbon triple bond are called alkynes.

✴ Saturated Hydrocarbons : Saturated hydrocarbons are hydrocarbons that contain only single bonds between carbon atoms. They are the simplest class of hydrocarbons. They are called saturated because each carbon atom is bonded to as many hydrogen atoms as possible. Alkanes are saturated hydrocarbons.

Answer 2

Explanation:

The compound in which the valency of all the atoms is either satisfied by the double or triple bond is called unsaturated hydrocarbon.

Examples:- ethene, propyne.
