Question

Write the molecular formula of alcohol which is drived from pentane.

Answer 1

Pentane is a saturated hydrocarbon whose general formula is ${\mathrm{C}}_5{\mathrm{H}}_{12}$.

If one Hydrogen $\left(\mathrm{H}\right)$ atom is removed and one Hydroxyl group $(-\mathrm{OH})$ is added to Pentane then, alkane is converted into alcohol.

Hence, Pentanol is formed and its molecular formula is ${\mathrm{C}}_5{\mathrm{H}}_{11}\mathrm{OH}$.
