Question

Which of the possible molecules/species is having maximum values for dipole moment (where " A" is the central atom)?

• A. $A{X}_3${having one lone pair on central atom}
• B. $A{X}_4${tetrahedral}
• C. $A{X}_3${having no lone pair on central atom}
• D. Cannot be predicted

Answer 1

Answer: (D)

Cannot be predicted

Values of dipole moment cannot be predicted as we do not know about the elctronegativities of the atoms.
