Answer to Question #104754 in Organic Chemistry for Blessing Akah

Question

State the hybridization,bond angle,polarity and decided whether their dipole moment will be zero or non zero.1.XeO4 .2. IF5. 3. XeF4. 4. SF 5.XeF4

Answer 1

1. XeO4

Hybridization - sp3, bond angle -109.5, dipole moments cancel our , the molecule is nonpolar.

Lewis structure is

Electron and molecular geometry is tetratedral:

2.IF5

Hybridization - sp3d2, bond angle less than 90 as lone pair pushes the bonds away, the molecule is polar as dipole moment do not cancel as there is asymmetric charge distribution on the central atom.

Lewis structure is

Molecular geometry is square pyramidal

3 and 5 are the same molecules XeF4

Hybridization - sp3d2, bond angle = 90, the molecule is nonpolar as dipole moment cancel out

Lewis structure

Molecular geometry - square planar

4.SF4

Hybridization - sp3d, bond angle less then 120 and less then 90 as lone pair pushes the bonds away, the molecule is polar as dipole moments do not cancel out due to the asymmetric charge distribution on the central atom.
