Which has a triple bond?
Think it through first, then pick an option.
- a H₂
- b O₂
- c N₂
- d Cl₂
Answer and explanation
Correct answer: c N₂
Correct. N (2, 5) is three short of an octet, so each shares three electrons: N≡N.
Why the other options are wrong
- a H₂: H₂ has one bond (H-H).
- b O₂: O₂ has two bonds (O=O).
- d Cl₂: Cl₂ has one bond (Cl-Cl).
