For each of the following bonds, indicate the positive end with \delta^{+} and the negative end with \delta^{-}. Write an arrow to show the dipole for each.
1. Si-Cl
2. Se-F
3. Br-F
4. N-H
5. N-P

    Look up the electronegativities of each pair. The higher EN will have a negative charge; the smaller EN will have a positive charge. So you can write delta - on the negative end and delta + on the positive end. For example,
    N-H. EN for N is about 3.0 and H is about 2.1. That makes N the negative end and H the positive end.
