Question

In the structure of $I{F}_7$ (lodine heptafluornde)_________.

• A. $d_{xy},d_x,d_z$ orbitals are involved in hybridisation
• B. axial bonds are longer than equitorial bonds
• C. there are $10$ different orghogonal angies
• D. the resullant geometry is a decahedral

Answer 1

Answer: (B)

axial bonds are longer than equitorial bonds

$I{F}_7$ has 7 bond pairs making it pentagonal bipyramidal which has the axial bonds longer than the equatorial ones.
