bond order

Postby Dahriel Aron 3A » Wed Oct 28, 2015 8:01 pm

Is a molecule more stable with a larger bond order? I thought that bond order correlated with the type of bond (single, double, triple) and that the more bonds there were the shorter the bond was, and the less stable it was. But do short bonds mean that the bond is more stable? In the practice quiz in the green book (pg 34 number 5) the answer implies that the larger the bond order is, the more stable the bond is.

Yes, the higher the bond order, the stronger the bond (more stable).

Bond order is calculated using MO theory so from my knowledge, bond order is not directly equal to the type of bond. You can have a bond order of 0 (Be2) or a bond order of 0.5 (F2-) even though you can't have a 0 or 1/2 bond between two atoms.
