Question

If there are 1652 kJ of bond energy in methane, how much energy is there in a single Carbon - Hydrogen bond?

Answer 1

The energy in a single Carbon - Hydrogen (C-H) bond of methane is 413 kJ

Bond energy

From the question, we are to determine the Carbon - Hydrogen bond energy in methane

From the given information,

The total bond energy in a molecule of methane is 1652 kJ

C-H bond energy = $\frac{Total\ bond\ energy\ in\ methane}{number\ of \ C-H \ bonds}$

Number of C-H bonds in methane = 4

Therefore,

C-H bond energy = $\frac{1652}{4}$

C-H bond energy = 413 kJ

Hence, the energy in a single Carbon - Hydrogen (C-H) bond of methane is 413 kJ
