dantate of double/single bonded oxygen

Postby May Xiao 1H » Sat Dec 08, 2018 9:18 am

CO3^2-
there're two single bonded oxygen and one double bonded oxygen.
Is it true that only single bonded oxygen (3 lone pairs) can be counted as one dantate? and why? because the double bonded oxygen also have 2 lone pairs right?

Because of the pi bond between C=O, you wouldn't expect the oxygen lone pair to interact since electron density is delocalized across that double bond.
