Identify the correct resonance structures of carbon dioxide from one given below
Choose the correct option:
1. (a, b)
2. (b, c)
3. (c, d)
4. (b, d)
Hint: A structure with a negative charge on the more electronegative atom will be more stable.
Resonance is a way of describing delocalized electrons within certain molecules or polyatomic ions where the bonding cannot be expressed by a single Lewis formula. A molecule or ion with such delocalized electrons is represented by several resonance structures.
The resonating structure of CO2 are:
O=C=O ↔ +O≡C−O− ↔ -O−C≡O+
