Question

Which of the following structures has a dipole moment in terms of atom and unbonded electron pair placement from a Lewis Dot structure view?

• A. $I{F}_4^{1-}$
• B. $Xe{F}_4$
• C. $I{F}_4^{1+}$
• D. $N{H}_4^{1+}$

Answer 1

The correct option is C $I{F}_4^{1+}$

${IF}_4^{+}$ has a net dipole towards $F$ as fluorine is more electronegative than iodine. Thus, fluorine pulls the $e^{-}$ density towards itself.
