The total number of lone pairs of electrons on oxygen atoms of ozone is

Question

Canvas Classes · Accepted Answer

Ozone () structure:

Step 1 — Draw Lewis structure of :
 (resonance hybrid)

The central O: 1 double bond + 1 single bond + 1 lone pair
Terminal O (double bond side): 2 lone pairs
Terminal O (single bond side): 3 lone pairs (with negative charge)

Step 2 — Count lone pairs on OXYGEN ATOMS only:
- Central O: 1 lone pair
- Terminal O (=O): 2 lone pairs
- Terminal O (−O⁻): 3 lone pairs

Wait — the question asks for lone pairs on oxygen atoms (all three oxygens):
Total = 1 + 2 + 3 = 6 lone pairs on
