Question

Resonance structures of a molecule have
Options
A same arrangement of atoms
B different arrangement of atoms
C same number of paired electrons
D A and C
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Resonance structures differ only in the position of electrons (pi electrons and lone pairs), not in the arrangement of atoms. The total number of paired electrons (and thus the total charge) remains the same.

Hint

What changes between resonance structures? What stays the same?
