Chemistry - CHEMICAL BONDING Question with Solution | TestHub

Same-element bonds occur in H₂O₂(O–O), H₂S₂O₈(O–O), N₂O(N–N), C₂H₆(C–C): four, not three. Oxygen is mixed−1/−2 in peroxodisulfuric acid only; H₂O₂ contains only−1 oxygen. Therefore B is false. H₄P₂O₇ supplies the sole P–O–P bridge. H₂O, SO₂, CO₂, N₂O are all triatomic and planar, giving four, so D is also false. Only C is correct after all count checks.
