Q. 5.6 g of an organic compound on burning with excess of oxygen gave 17.6 g of $C O_{2}$ and 7.2 g of $H_{2} O$ . The organic compound is:

$C_{6} H_{6}$

$C_{4} H_{8}$

$C_{3} H_{8}$

$C H_{3} COO H$

$C H_{3} C H O$

$O r g ani c co m p o u n d [O] 17.6 g C O_{2} + 7.2 g H_{2} O$
% of $C = \frac{12}{44} \times \frac{17.6}{5.6} \times 100 = 85.7$ %
% of $H = \frac{2}{18} \times \frac{7.2}{5.6} \times 100 = 14.28$ %
