Best answer. PCL XL has a closer relationshipt to the GDI used within Windows than does PCL5; most PCL6 drivers now offer more features than their PCL5 equivalents. In the olden days it was said that PCl5 could form and NCl5 couldn't because nitrogen had no empty d-orbitals (no such thing as a 2d orbital) with which to form hybrid orbitals. Therefore, NCl 5 does not exist. ya the reason is this that P is so small in size than I therefore PI5 not known. Since the valence shell of nitrogen has n=2, therefore, it cannot have d-orbitals. Hence PCl 5 exists.
In contrast, electronic configuration of N is, . Thus, P has empty 3d orbitals to

'I was suffering': Thicke on painkiller abuse 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. It does not have d orbitals to expand its covalency beyond four. to Euclids Geometry, Areas to Three Dimensional Geometry, Application (ii) âPâ has ef-orbitals, whereas âNâ does not have cf-orbitals. Phosphorous has d-orbitals and hence can accommodate the electrons from Cl into them, Incase of N the d-orbitals are absent and electrons can be accommodated only in p- ornitals. Normally, names of ionic compounds do not use these prefixes to indicate the number of positive or negative ions. pcl5 is known but ncl5 is not known?
