Question

Calculate the bond dissociation energy (in kJ/mol) required to break the carbon-hydrogen bond in methane using the given bond dissociation energies: C-H = 413 kJ/mol, C-C = 347 kJ/mol, C=C = 602 kJ/mol, H-H = 436 kJ/mol.

Answer 1

The bond dissociation energy required to break the carbon-hydrogen bond in methane is already given in the problem statement. The C-H bond dissociation energy is 413 kJ/mol. There is no need to use the other bond dissociation energies  C-C, C=C, and H-H  as they are not relevant to breaking the C-H bond in methane.
