Question
For a hydrocarbon, the ratio of volume O2 used for complete combustion and the volume of CO2 formed is independent to the number of carbon atoms present in the hydrocarbon. The hydrocarbon may be
Options
A.Alkane
B.Alkene
C.Alkyne
D.Arene
Solution
$C_{x}H_{y} + \left( x + \frac{y}{4} \right)O_{2} \rightarrow xCO_{2} + \frac{y}{2}H_{2}O$
From question, $\frac{\left( x + \frac{y}{4} \right)}{x}$= Independent of x.
For alkene, y = 2x.
