### When to Use Formal Charge

How do you determine when to use the formal charge formula to draw your structures? And does the one with the most negative formal charge go on the left or right?

u should always calculate formal charge because it can help you find the most stable form of a molecule.

always use formal charge, and then try to create a structure that ends up with lowest formal charge/FC that matches the molecule. also try to arrange the molecule so that all the FC on each element is closest to 0

Formal charge tells you which resonance structure is more stable so with it you'll be able to find the preferred form of a molecule

Calculating formal charge is useful when trying to draw the most stable structure as possible. The negative formal charge should go on the most electronegative atom.
