Bond Enthalpies of Diatomic Molecules

Postby Linh Vo 2J » Mon Jan 28, 2019 11:40 am

Why are bond enthalpies of diatomic molecules accurate but using bond enthalpies is the least accurate method for all others?

Because the bond enthalpies of other molecules are averages

Since diatomic molecules are the most stable form of those elements, those elements pretty much only occur in that state, so the bond enthalpies are known an accurate. Bonds between other elements, like Carbon for example, can be found in multiple different molecules. Therefore the enthalpies of these bonds are averages of that bond in all the molecules it can occur.
