The compounds FCl and ICl have dipole moments $\backslash$mu that are similar in magnitude $(0\mathrm{.}9$ and $0\mathrm{.}7$ D$,$ respectively$)$ but opposite in direction. In one compound, chlorine is the positive end of the dipole; in the other it is the negative end. Specify the direction of the dipole moment in each compound, and explain your reasoning.
