For each of the following molecules, predict the molecular shape, give bond angles, hybridization and determine whether the molecule will be polar or non-polar.

a. CF4

b. BeH2

c. SeF6

d. XeOF2

Expert Solution

Molecule CF4

Molecular shape: Tetrahedral

Bond angle: 109.5o

Hybridization: sp3

Polarity: Non-polar [Dipole moments of individual C-F bond will cancel out each other, resulting the molecule non-polar.]

Molecule: BeH2

Molecular Shape: Linear

Bond angle: 180o

Hybridization: sp

Polarity: Non-polar [Be-H dipoles are oriented in opposite direction, they will cancel out each other resulting the molecule non-polar.]

Molecule: SF6

Molecular shape: Octahedral

Bond angle: 90o

Hybridization: sp3d2

Polarity: Non-polar [Individual S-F bonds are polar but oriented in opposite direction, they will cancel out each other resulting the molecule non-polar.]

Molecule: XeOF2

Molecular shape: T-Shape

Bond angle: F-Xe-O = 90o and F-Xe-F = 180o

Hybridization: sp3d

Polarity: Polar [Xe-F dipoles are oriented in opposite direction, they will cancel out each other but the polar Xe=O bond is responsibe for molecular polarity.]
