Question

The elemental composition of a compound is $54.2 \% \mathrm{C}, 9.2 \% \mathrm{H}$ and $36.6 \% \mathrm{O}$. If the molar mass of the compound is $132 \mathrm{~g}_{13} \mathrm{~mol}^{-1}$, the molecular formula of the compound is :
[Given : The relative atomic mass of $\mathrm{C}: \mathrm{H}: \mathrm{O}=12: 1: 16$ ]

Select the correct option:

$\mathrm{C}_{4} \mathrm{H}_{8} \mathrm{O}_{2}$

$\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}$

$\mathrm{C}_{4} \mathrm{H}_{9} \mathrm{O}_{3}$

$\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{3}$
