question 4.25 in ochem book

Postby Miya Eberlein 1J » Fri Feb 26, 2016 2:42 pm

Hi! for question 25 in chapter 4 we're supposed to use curved arrow to indicate electron movement in the reaction. In this case our nucleophile is Br2. I was wondering why one Br molecule is more electronegative than the other one, as shown in the answer key. Thank you!

At some very short time, electron can "lean" toward one atom and make it slightly negative and leaves the other slightly positive.
