The structure of

IF_{7}

is :

(A)trigonal bipyramid
(B)octahedral
(C)pentagonal bipyramid✓ Correct
(D)square pyramid

Answer: (C)

Solution

I F_{7}

the central iodine has seven bonding pairs and no lone pair, a steric number of seven answered by

s p^{3} d^{3}

hybridisation. Seven bonds with no lone pairs arrange themselves as a pentagonal bipyramid, with five fluorines in the equatorial pentagon and two along the axis.
