The first step is that the ionic compound is broken down due to the polarity of the surrounding water molecules with oxygen being electronegative and hydrogen being electropositive. Hence, the Ionic bond has been broken. The second step is that both … 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. pencil case and stationery
