Question

$11.6 g$ of an organic compound having formula $C_{n} H_{2 n + 2}$ is burnt in excess of $O_{2} (g)$ initially taken in a $22.41$ litre steel vessel. Before reaction the gaseous mixture was at $273 K$ with pressure reading $2 a t m$ . After complete combustion and loss of consideration amount of heat, the mixture of product and excess of $O_{2}$ had a temperature of $546 K$ and $4.6 a t m$ pressure. The formula of organic compound is:

C_{2} H_{6}
