Which one of the following formulae does not correctly represent the bonding capacities of the two atoms involved?

1. H — P — H
2. F — F
3. O = N — O
4. H — C ≡ C — O — H

Correct answer: O = N — O

Solution

Option C (O = N — O) is incorrect because nitrogen cannot form five bonds as it violates the octet rule. The structure is not chemically valid.
