Best answer. PCl5 has 10 electrons around P, using 3d orbitals in addition to the usual 3s and 3p.
In contrast, electronic configuration of N is, . These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. Hence, PCl 4 +1 compound is more likely to exist. Nitrogen can not extend its valence from 3 to 5 due to absence of d orbital while phosphorous shown penta valence as d-orbital are present in its valence cell. N is too small to allow this structure.
