🤓 Based on our data, we think this question is relevant for Professor Enderle's class at UCD.
We have to determine which of the given Lewis structures is a better structure.
A better Lewis structure is the one which has the smallest possible formal charges on all the atoms in the molecule.
Formal charge is the charge assigned to an atom in a Lewis structure assuming that the electrons in the chemical bonds are shared equally between atoms.
Formal charge is calculated by this formula:
Use formal charges to identify the better Lewis structure.
