The species, which have less than 8 electrons in the valence shell or the species, which have 8 valence electrons, but has empty d orbitals, so that the covalency can be spread beyond 4, are called as electron deficient species.
BCl3 is electron deficient compound because boron has only 6 valence electron and is short of 2 electrons. Therefore it can accept a pair of electrons from nucleophiles. SiCl4 is not electron deficient compound because silicon has 8 valence electrons. It cannot spread its covalency beyond 4 because silicon doesn’t have d- orbitals.
