All of the atoms of a saturated hydrocarbon are bonded by 1 or 2 pair(s) of electrons.

Explanation:

A hydrocarbon is defined as a specie which contains atoms of carbon and hydrogen.

For example, is a hydrocarbon.

When there are only single bonds present in a hydrocarbon then it is known as a saturated hydrocarbon.

When a hydrocarbon contains a double or triple bond then it is known as an unsaturated hydrocarbon.

For example, is an unsaturated hydrocarbon.

Therefore, we can conclude that the statement all of the atoms of a saturated hydrocarbon are bonded by 1 or 2 pair(s) of electrons, is not true.
