Abstract:Lower and upper bounds are derived for bond number, localization energy and atom self-polarizability of alternant hydrocarbons. It is proved that in acyclic polyenes the maximal bond number is 1, radic2 and radic3, respectively for primary, secondary and tertiary carbon atoms.
Keywords:Graph theory  Free valence  Localization energy  Polarizability
