The resonating structures of acetate ion are labelled I, II and III as shown below.
Choose the correct order of their relative stability (contribution to the resonance hybrid).
Options:
Answer:
A
Solution:
I and II are equivalent (the negative charge sits on either oxygen) and have complete octets. III has a carbon with only six electrons and one more negative charge on oxygen, so it contributes least. Order : I = II III.
