What exactly is the correlation between electronegativity, bond strength, and stability? and flemish bond DSCN0499

What exactly is the correlation between electronegativity, bond strength, and stability?



I read in my textbook that the electrons in a C-H bond in a carbohydrate, for example, are less tightly held and have more energy than double bonded Carbon and Oxygen bonds. It also stated that these C-H bonds were unstable, while the C=O bonds were stable. I'm really confused now because I always thought that stability means unreactive, so according to this book, that would make the C-H bonds reactive. How could this be???


Bond best answer:

Answer by Lance
You are right in that a stable bond is unreactive.

In this case, you are looking at the relative reactivity of the bonds. A C-H bond is more reactive (unstable) than a C=O bond. This does not mean that a C-H bond reacts easily; it just means that the C=O bond is more stable than a C-H bond.
