Bond strength of c-c

WebBelow are average bond lengths and strengths for all types of carbon-to-carbon bonds. You might notice that the double bond for two carbons is not actually double strength - it's more like 1.5× a single, and a triple bond is more like 2.5× a single. So in this case, a triple bond isn't triple strength, but it is definitely a lot more. WebJun 25, 2010 · But the bond strengths here are alkyne C-H (523 kJ/mol or 125 kcal/mol) versus the tertiary C-H bond strength in this case (384 kJ/mol or 93 kcal/mol). So why is the C-H bond with the lower bond …
