bond length and bond energy

Question

Arrange the following bonds in order of increasing bond length: C-C, C=C, C≡C

RankGuru · Accepted Answer

**Bond Length** is inversely proportional to the **Bond Order** (number of shared electron pairs).
- **C≡C** (Triple bond, order 3) has the strongest attraction between atoms, pulling them closest ($\approx 120 	ext{ pm}$).
- **C=C** (Double bond, order 2) is longer ($\approx 134 	ext{ pm}$).
- **C-C** (Single bond, order 1) is the longest ($\approx 154 	ext{ pm}$).
- Order: $Triple < Double < Single$.
