Consider the following compounds:

(i) \[I{{F}_{5}}\]

(ii) \[ClI_{4}^{-}\]

(iii) \[Xe{{O}_{2}}{{F}_{2}}\]

(iv) \[NH_{2}^{-}\]

(v) \[BC{{l}_{3}}\]

(vi) \[BeC{{l}_{2}}\]

(vii) \[AsCl_{4}^{+}\]

(viii) \[B{{(OH)}_{3}}\]

(ix) \[NO_{2}^{-}\]

(x) \[ClO_{2}^{+}\]

The value of "x + y - z" is where x, y and z are total number of compounds in given compounds in which central atom used their all three p- orbitals, only two p-orbitals and only one p-orbital in hybridisation respectively.
