Draw the best Lewis structure for IF4⁻ and answer following questions. 1) How many single bond, how many double bond and how many triple bond does this ion have?  2) What’s the molecular geometry of the ion (molecular geometry only)?  3) Apply Valence Bond Theory, determine which orbitals overlap to form I-F bond (use sigma or pi for bond type, followed by atom(overlapping orbital).  For example, write sigma: O(sp3)-H(s) for O-H bonds in H2O molecule.   Mark your answer next to words “Final answer is”.
