Problem: Iodine forms a series of fluorides (listed here). Write Lewis structures for each of the four compounds and determine the formal charge of the iodine atom in each molecule:(a) IF(b) IF3(c) IF5(d) IF7

FREE Expert Solution

We’re being asked to determine the formal charge of iodine in IF, IF3IF5, and IF7.


To do so, we need to do the following steps:


Step 1: Determine the central atom in the molecule.

Step 2: Calculate the total number of valence electrons present.

Step 3: Draw the Lewis structure for the molecule.

Step 4: Calculate the formal charge for the indicated atom.


 Recall that the formula for the formal charge is:


F.C.=Group No. -Bonds+Nonbonding electrons
