Question

Shape and hybridization of `IF_5`, respectively, are
A. Trigonal bipyramidal, `sp^3d`
B. Seesaw, `sp^3d`
C. Square pyramidal, `sp^3 d^2`
D. Pentagonal pyramidal, `sp^3 d^3`

Answer 1

Correct Answer - C
I atom has seven 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 electrons around I, hybridization is `sp^3 d^2`.
