Rules for Resonance Stability
Step 2: Evaluating Structures
- (I) : Neutral, all atoms have complete octets. Most stable.
- (II) : Negative charge on Oxygen (electronegative).
- (III) : Negative charge on Carbon and positive on Oxygen. This is highly unstable as Oxygen is more electronegative than Carbon.
Step 3: Order (I) > (II) > (III).
