The Stability

<div> <p>A quantum chemical investigation of the stability of compounds with identical formulas was carried out on 23 classes of compounds made of C, N, P, O, S atoms as core structures and halogens H, F, Cl, Br, I as substituents. All possible structures were generated and investigated by quantum mechanical methods. The prevalence of a formula in which its <i>Z</i> configuration, <i>gauche</i> conformation or <i>meta</i> isomer is the most stable form is calculated and discussed. Quantitative and qualitative models to explain the stability of 23 classes of halogenated compounds were also proposed.</p></div>
