Generally, a triple bond is the strongest, then a double bond, then a single bond.
Reason: more shared electron pairs (higher bond order) increase the net attraction between the bonded nuclei and the shared electrons, giving a shorter bond length and higher bond dissociation energy.
Typical examples (approximate bond dissociation energies):
- C–C (single) ≈ 350 kJ/mol
- C=C (double) ≈ 610 kJ/mol
- C≡C (triple) ≈ 840 kJ/mol
Caveat: “strongest” depends on which atoms are bonded and the molecular environment. For example, H–H (~436 kJ/mol) is stronger than some C=C bonds, and N≡N (~945 kJ/mol) is exceptionally strong. So the order single < double < triple holds as a general rule for the same pair of atoms.
