Question

What is the molecular formula for butane?

Answer 1

Alkane

• The general molecular formula of alkane is $C_{\text{n}}{\text{H}}_{2\text{n}+2}$.
• Here, $\text{n}$ is the number of the carbon atom.

Molecular formula for butane

• In butane, the value of a carbon atom is four.
• Hence, the molecular formula for butane is $C_4{\text{H}}_{2\times 4+2}$ that is ${\text{C}}_{\text{4}}{\text{H}}_{\text{10}}$.

So, the molecular formula of butane is ${\text{C}}_{\text{4}}{\text{H}}_{\text{10}}$.
