New relations are proposed for the determination of bond dissociation energies of diatomic alkali-earth halides. The relations are[Formula: see text]and[Formula: see text]where [Formula: see text], Δx represents Pauling's electronegativity differences (XA − XB) and rc is the internuclear distance. The estimated bond energies are in reasonably good agreement with the literature values. The errors calculated with our suggested relations for bond energies are 9.9% and 7.5% respectively. The corresponding errors evaluated from Matcha's and Pauling's equations are 6.1 % and 48.2%, respectively. A simplified formula for the determination of bond orders of alkali-earth halides has been suggested. The formula has the form [Formula: see text]. The definition for bond order given by Parr and Borkman differs from that given by Politzer. Thorough investigation of the two statements reveals that the Politzer's definition is a better one.


There is little ambiguity when one speaks of bond lengths, but the term ‘bond energy’ has been given several interpretations and it would be useful if we had these in mind in our discussion. In the beginning it was a useful simplification to assume as did Fajans that the energy required to break a particular bond was a constant characteristic of that bond and independent of the molecular environment. Now we know that this is not the case and indeed a great part of our discussion will be concerned with the differences in bond dissociation energies.
