Question

In ${CH}_4$ molecule, which of the following statements is correct about the $C-H$ bond energy?

• A. All $C-H$ bonds of methane have same energy
• B. Average of all $C-H$ bond energies is considered
• C. Fourth $C-H$ bond requires highest energy to break
• D. None of the above

Answer 1

The correct option is B Average of all $C-H$ bond energies is considered

While considering the bond energy of the molecule, we have to consider all atoms,

in $C{H}_4$ molecule, we are having 4 $C-H$ bond and all are having the same energy because they have same bond multiplicity and electronegativity.
