The number of inter halogens from the following having square pyramidal structure is ClF 3 ,   IF 7 ,   BrF 5 ,   BrF 3 ,   I 2 Cl 6 ,   IF 5 ,   ClF ,   ClF 5

Correct answer

3

Step-by-step solution

Square pyramidal structures are BrF 5 , IF 5 and ClF 5 . These molecules are made up of 6 equally spaced sp 3 d 2 hybrid orbitals arranged at 90 o angles. The shape of the orbitals is octahedral. One orbital contains a lone pair of electrons, so the remaining five atoms connected to the central atom gives the molecule a square pyramidal shape. Among the given options the structure with five bond pairs and one lone pair is these three structures only.
