4.25 charge difference?

Postby Jana Sandhu 3J » Mon Feb 29, 2016 11:51 pm

On question 4.25, one of the species involved is Br2. The solution shows that there is an electronegativity difference between the two bromine molecules, saying one is more negative and the other more positive. Why is this so considering it is the same element bonded to itself? Shouldn't there be no difference in charge?

Just like HBr can be polarized, Br2 can be polarized as well to create a partially positive bromine and a partially negative bromine.
