Abstract

Structural differences of 1,2-dihaloethanes H2XCCXH2 (X F, Cl, Br, I) have been studied theoretically by the sp-CNDO/2 method. The reliability of this approach was tested on the corresponding ethenes, HXCCXH. It is shown that geometries determined in terms of mean values, e.g. from electron diffraction, and referring to a conformational equilibrium, may conceal important differences in bond angles of the individual conformers. Moreover, the determination of the angle of internal rotation may be considerably affected.
