Abstract: All staggered and eclipsed conformations of 1,2-ethanediol, 2-aminoethanol, and 1,2-ethanediamine were studied by the semiempirical CNDO/2 method with optimization of structural parameters. The conformations of the -OH and -NH₂ functional groups were also investigated. The results obtained are compared with available exptl. and theor. data. The energy of particular conformations is mainly influenced by interat. repulsion and possible formation of intramol. H bond.
