Select the correct statement regarding shapes of `PCl_(5), BrF_(5)` & `IF_(7)` :

Options

A. All are square pyramidal
B. All are trigonal bipyramidal
C. One of the following is square pyramidal
D. one of the following is tetrahedral

Answer

C

Explanation

`PCl_(5)`

`bp = 5`
`Ip = 0`
Total `= 5`
`sp^(3)d`
Trigonal bipyramidal
`BrF_(5)`

bp = 5
Ip = 1
Total = 6
`sp^(3)d^(2)`
square pyramidal
`IF_(7)`

bp = 7
Ip = 0
total = 7
`sp^(3)d^(3)`
pentagonal bipyramidal.
