Solution

If the valency of carbon is 4 and that of hydrogen is 1 then the molecular formula of methane is ${CH}_{4}$

Valency is the combining property of an atom. It is a measure of how many hydrogen atoms it can combine with.

For example, oxygen can combine with two hydrogen atoms and create a water molecule. So, the valency of the oxygen atom is two. Methane has one carbon atom combined with four hydrogen atoms to form a methane ( ${CH}_{4}$ ) molecule.
