Work Step by Step
Polar Molecules (Have Net Dipole Moments)
1) XeCl₂ (Xenon dichloride)
Shape: Linear
Electron domains: 5 (2 bonding + 3 lone pairs)
Reason: Despite being linear, the lone pairs create asymmetry → polar
2) ICl₃ (Iodine trichloride)
Shape: T-shaped
Electron domains: 5 (3 bonding + 2 lone pairs)
Reason: Asymmetrical shape → polar
3) TeF₄ (Tellurium tetrafluoride)
Shape: See-saw
Electron domains: 5 (4 bonding + 1 lone pair)
Reason: Asymmetrical geometry → polar
d) ICl₅ (Iodine pentachloride)
Shape: Square pyramidal
Electron domains: 6 (5 bonding + 1 lone pair)
Reason: Asymmetry due to lone pair → polar
Nonpolar Molecules (No Net Dipole Moment)
5) PCl₅ (Phosphorus pentachloride)
Shape: Trigonal bipyramidal
Electron domains: 5 bonding
Reason: Symmetrical geometry → nonpolar
6) XeCl₄ (Xenon tetrachloride)
Shape: Square planar
Electron domains: 6 (4 bonding + 2 lone pairs)
Reason: Symmetrical planar shape → nonpolar
7) SeCl₆ (Selenium hexachloride)
Shape: Octahedral
Electron domains: 6 bonding
Reason: Perfect symmetry → nonpolar
