stability - Why is a C–D bond stronger than a C–H bond?

WebKeeping the overlap of orbitals in mind, the bond in molecular hydrogen is average as far as covalent bonds go. Molecular oxygen's double bond is stronger at 498 kJ/mol primarily because of the increased orbital overlap from two covalent bonds. And this idea continues with molecular nitrogen which has a triple bond and a bond energy of 945 kJ/mol. WebFor example, the bond energy of the carbon-hydrogen bond in a methane (CH 4) molecule is equal to the average of the bond dissociation energies of each individual carbon …
