Abstract

This paper discusses in detail the calculation of bond lengths of organic molecules in the solid state It describes briefly the effect of electronegativity in covalent bond length A set of single bond covalent radii and electronegativity values are proposed Covalent bond lengths calculated by a modified form of the soft sphere equation which calculated internuclear separation of different Group 1 and Group 2 crystalline salts to a remarkable degree of accuracy show very good agreement with observed values The results also show that electronegativity is a major influence on covalent bond lengths and the soft sphere model described here can be used to calculate covalent bond lengths of other organic bio-organic molecules in different environments that have not yet been experimentally measured
