Electron Deficient Molecules

The electron deficient molecule may be defined as a molecule in which there are not enough bonding electrons available to join all the atoms in the molecule together by normal covalent bonds [i. e., electron pair bonds). In other words, electron deficient molecules may also be defined as molecules or substance in which the atoms have more stable orbitals in the valence shell than the electrons.

For example, beryllium chloride is collinear in the vapour state and polymerised in solid state in which each beryllium atom is bonded tetrahedrally to four chlorine atoms, so filling, by coordinate bond two 2p-orbitals of beryllium which were vacant in discrete $BeCl_2$ molecules. Similarly, aluminium chloride $(AlCl_3)$ also dimerizes $AI_2CI_6)$ in organic solvents. Boron hydride and halides are also electron deficient molecules.
