Question

Which one of the following is the strongest bond?
(a) > C = C < (b) — C ≡ C —
| | |
(c) — C — C = (d) — C — C —
| | | |

Answer 1

Explanation:

The correct sequence of the bond energy of C-CC−C, C=CC=C, and C\equiv CC≡C bonds is C\equiv C > C=C > C-CC≡C>C=C>C−C.

The bond energy of carbon carbon triple bond is maximum as it is the strongest bond. The bond energy of carbon carbon single bond is minimum as it is the weakest bond.

Hence, the correct option is D.
