best lewis structure

Postby Savannah Mance 4G » Sun Dec 08, 2019 12:06 am

If the atoms in a lewis structure have formal charges that add to zero is this more stable than having one atom with a formal charge of 0 and the other with a charge? Like say for (C2)-2. You could have a double bond and have a carbon with a 2+ charge and carbon with 0 or a triple bond and have a charge of 1- on one carbon and 1+ on the other.

For lewis structures you should always work towards the lowest possible over all charge of the compound. but if it is an ion you should match the charges and if oxygens are present any negative charges are better on oxygen as it is more accepting of a negative charge due to its higher electronegativity.
