Shape and hydridisation of `IF_(5)` respectively are

Options

A. Trigonal bipyrmidal ,`sp^(3) d `
B. See saw, `sp^(3) d `
C. Square pyramidal, ` sp^(3) d^(2)`
D. Pentagonal pyramidal , ` sp^(3) d^(3)`

Answer

c

Explanation

I atom has 7 electrons in the valence shell . 5 of these are shared with 5F atoms . One lone pair is present .
Thus , around I, there are 5 bond pairs and one lone
pair . Hence , geometry is square pyramidal . As there
are total 6 elelctron pairs around I, hybridisation is ` sp^(2) d^(2)` .
