  • Electron deficient Hydrides are those Hydrides in which the central atom has less than 8 electrons in the outer-most shell. For example, BH3.
  • Electron precise Hydrides are those Hydrides, in which the central atom has 8 electrons in its outer most shell, as per octet law. For example, CH4 etc.
  • Electron rich Hydrides are those Hydrides, in which central atom contains one or more than lone pair of electron. For example, PH3 etc.
