double bonds

Postby sid bauer » Fri Jul 21, 2017 6:41 am

So after practicing Lewis Structure, I've realized some atoms such as S, C and O create double bonds more often than others. What is the reasoning behind that?

In the end, it's all to satisfy the octet rule. It just so happens that for these elements and the way our universe is, a lot of compounds involving these elements will end up with double bonds on these atoms.

For an atom such as Oxygen and Sulfur, a double bond is sometimes needed in order to satisfy a full bond and to achieve a 0 (most stable) formal charge.
