Question

A gaseous alkane is exploded with oxygen. The volume of O2 required for complete combustion and volume of CO2 gas produced at same pressure and temperature are in 8:5 ratio. The hydrocarbon is - (A) C4H10 (B) C5H10 (C) C4H8 (D) C5H12

CnH2 n + 2+((. 3 n + 1 .)/2)O2 arrow (nCO)2+(nH)2O (VO2/ V(CO)2)=(((. 3 n + 1 .)/2)/n)=(3 n + 1/2 n)

Q. A gaseous alkane is exploded with oxygen. The volume of $O_{2}$ required for complete combustion and volume of $C O_{2}$ gas produced at same pressure and temperature are in $8 : 5$ ratio. The hydrocarbon is -

$C_{4} H_{10}$

$C_{5} H_{10}$

$C_{4} H_{8}$

$C_{5} H_{12}$

$C_{n} H_{2 n + 2} + \frac{( 3 n + 1 )}{2} O_{2} \to (n CO)_{2} + (n H)_{2} O$
$\frac{V _{O_{2}}}{V _{(CO)_{2}}} = \frac{\frac{( 3 n + 1 )}{2}}{n} = \frac{3 n + 1}{2 n}$
