Resonance in carbonate ion (CO₃²⁻): Which is true?
General Organic Chemistry (GOC) · Class 11 · JEE Main Previous Year Question
Resonance in carbonate ion (CO₃²⁻):
Which is true?
- a
It is possible to identify each structure individually by some physical or chemical method
- b
All these structures are in dynamic equilibrium with each other
- c
Each structure exists for equal amount of time
- d✓
CO₃²⁻ has a single structure i.e., resonance hybrid of the above three structures
CO₃²⁻ has a single structure i.e., resonance hybrid of the above three structures
Understanding Resonance in Resonance is a hypothetical concept and exists only on paper. It involves the delocalization of electrons within a molecule. The individual Lewis structures (canonical forms) are not real.
- Option D: The actual structure of the carbonate ion is a single, stable resonance hybrid of all three contributing structures, where all bonds are of equal length.
