well ... said dat coz .. at such a low temperature its only double bond dat can react... breaking a triplbe bond needs much more energy dats difficult to provide at that low temp.
so it reacts with bromine and becomes 4,5-dibromopentyne.

hmm.. more e- rich ... okie...
but breaking a triple is not easy ... thats y even if it attacks its not succesful ... (it = bromine)
