Which of the following on combustion gives maximum energy-EthanePropaneButaneMethane

Toppr Admin · Accepted Answer

Equation for combustion of alkanes is as followsCnH2n-2-3n-12-O2-x2192-nCO2-n-1-H2O-HeatGreater the value of n greater will be the heat produced- Therefore- on combustion butane gives maximum energy-

Equation for combustion of alkanes is as followsCnH2n+2+(3n+12)O2→nCO2+(n+1)H2O+HeatGreater the value of n greater will be the heat produced. Therefore, on combustion butane gives maximum energy.

Equation for combustion of alkanes is as follows
$C_{n} H_{2 n + 2} + (\frac{3 n + 1}{2}) O_{2} \to n C O_{2} + (n + 1) H_{2} O + H e a t$
Greater the value of n greater will be the heat produced. Therefore, on combustion butane gives maximum energy.
