Question

The different structures formed by resonance of compounds are known as :

• A. resonant
• B. resonance structures
• C. canonical forms
• D. all of the above

Answer 1

Answer: (B), (C)

The correct options are
B resonance structures
C canonical forms

In chemistry, resonance is a way of describing delocalized electrons within certain molecules or polyatomic ions where the bonding cannot be expressed by one single Lewis structure. A molecule or ion with such delocalized electrons is represented by several contributing structures (also called resonance structures or canonical structures).
