Which of the following on combustion gives maximum energy?

Options

  1. AEthane
  2. BPropane
  3. CMethane
  4. DButane

Correct answer

D. Butane

Step-by-step solution

Equation for combustion of alkanes is as follows C _ n H _ 2 n+2 + ( 3 n+1 2 ) O ₂ n CO ₂+(n+1) H ₂ O +Heat Greater the value of n greater will be the heat produced. Therefore, on combustion butane gives maximum energy.
