The ratio of mass percent of C and H of an organic compound ( C_X H_Y O_Z ) is 6: 1. If one molecule of the above compound ( C_X H_Y O_Z ) contains…
The ratio of mass percent of C and H of an organic compound $\displaystyle \left(\mathrm{C}_{\mathrm{X}} \mathrm{H}_{\mathrm{Y}} \mathrm{O}_{\mathrm{Z}}\right)$ is $\displaystyle 6$ : 1. If one molecule of the above compound $\displaystyle \left(\mathrm{C}_{\mathrm{X}} \mathrm{H}_{\mathrm{Y}} \mathrm{O}_{\mathrm{Z}}\right)$ contains half as much oxygen as required to burn one molecule of compound $\displaystyle \mathrm{C}_{\mathrm{X}} \mathrm{H}_{\mathrm{Y}}$ completely to $\displaystyle \mathrm{CO}_2$ and $\displaystyle \mathrm{H}_2 \mathrm{O}$. The empirical formula of compound $\displaystyle \mathrm{C}_{\mathrm{X}} \mathrm{H}_{\mathrm{Y}} \mathrm{O}_{\mathrm{Z}}$ is :
Official answer
(4)
$\displaystyle \mathrm{C}_2 \mathrm{H}_4 \mathrm{O}_3$
