Bounds for reactivity indices

  • Ivan Gutman
Original Investigations


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, √2 and √3, respectively for primary, secondary and tertiary carbon atoms.
