Which of the following statements is/are true? Correct the false statements.
a. The molecules SeS₃,SeS₂,PCl₅,TeCl₄, ICl ₃, and XeCl₂ all exhibit at least one bond angle which is approximately 120⁰.
b. The bond angle in SO₂ should be similar to the bond angle in CS₂ or SCl₂
c. Of the compounds CF₄,KrF₄, , and SeF₄, only SeF₄ exhibits an overall dipole moment (is polar).
d. Central atoms in a molecule adopt a geometry of the bonded atoms and lone pairs about the central atom in order to maximize electron repulsions.
