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.

The paper describes a pyrolytic method of investigating the kinetics of gaseous reactions in which toluene is used as a carrier gas. It is shown that the method is particularly suitable for the determination of bond dissociation energies. The scope of the method is illustrated by various examples. A list of bond dissociation energies obtained is given. The manner in which the experimental results obtained can be cross-checked, is indicated and illustrated by examples. The effects of various constitutional factors on the bond dissociation energies are discussed.
