We’re being asked to determine the best structure of nitrous acid by determining the formal charges of the atoms present.
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:
Which of the following structures would we expect for nitrous acid? Determine the formal charges:
