Reactivity and triple bond would seem to be opposite properties as triple bond sounds "extra stable". Reactivity would seem to make "electrochemistry" breakup of molecules easy, but this molecule doesn't seem to produce useful fuel, or compounds that are not easier to get by other means.
What is interesting about this molecule's reactivity?
I don't think triple bond means extra stability in all cases. Often its like flex taped something bulky into small area which is going to explode.. One of the triple bond may easily break and show reactivity.
Don't trust me I ain't chemist but extra stability is seen on N~2~ but not on C-C bonds IIRC
C-C triple bonds are also pretty stable, e.g. acetylene and other alkynes. C-B bonds on the other hand... I don't recall ever coming across one before today.
Bond strength isn't necessarily a measure of bond reactivity. Triple bonds are often quite reactive, and in certain contexts they're incredibly unstable and have unusual reactivity - see "benzyne"
Are benzynes really a triple bond, though, or are they more like a double bond with a "+" charge on one carbon and a "-" charge on the other?
I mean youre not wrong but this argument can be applied to an absolute ton of chemical functionalities. I don't have time to dig up evidence but I'm sure benzyne has been characterized spectroscopically to determine. I'd imagine it as a resonance structure of a triple bond and charge separated species like you would an ylide or sulfoxide, but neither is wrong
