Q. The structure of $IF_{5}$ can be best described as
A) [image:4_image64.emf]
B) [image:4_image65.emf]
C) [image:4_image66.emf]
D) None of these
Explanation
(c)
Number of hybrid orbitals $= no.of\ bp + no.of\ lp$
$= 5 + 1 = 6$
Thus, hybridization is $sp^{3}d^{2}$ but geometry, due to the presence of one pair, is square pyramidal, $ie$
