Polar bonds and boiling points

You will write three small functions. One finds the share of an electron charge across a bond. One picks the bond with the largest dipole moment, and another picks the bond with the largest share. The last predicts a boiling point from the trend of a series.

The idea. The dipole moment is charge times length, so the charge is the dipole moment divided by the length. A bond can have the largest dipole moment without having the largest charge.

Your tasks.

1. Complete charge_share(mu, length_pm) so that it returns the percentage of one electron charge that is separated.
2. Set largest_dipole to the halogen with the largest dipole moment, and largest_share to the halogen with the largest share.
3. Complete predict_bp(known, n) so that it returns the boiling point for n carbon atoms, from the average rise of the series.
