Chapter 8.7, Problem 8.11CYU

For each of the following pairs of bonds, decide which is more polar. For each polar bond, indicate the positive and negative poles. After making your prediction from the relative atom positions in the periodic table, check your prediction by calculating. ∆_X from electronegativity values in Figure 8.11.
