For bond dissociation energies (BDEs) of double and triple bonds, is number shown in tables for that second or third bond? Or all of them? Simple, 'dumb' question....   Is the kJ/mol number given in tables of bond strengths or bond dissociation energies , when it comes to double and triple bonds, just for the 'last' bond or for both (or all three) together?
They're for the entire bond (so for a triple bond, all 3).

From Wikipedia, it can be defined as 


  The standard enthalpy change when [a bond, be it single, double, or triple] is cleaved by homolysis to give fragments A and B, which are usually radical species


So you get two fragments as your final state.
