Problem: Determine the formal charge of each element in the following:(a) PCl3(b) PF5

FREE Expert Solution

We’re being asked to determine the formal charge of ALL ELEMENTS in PCl3 and PF5.

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
