$1\mathrm{.}59($modified$)$ Dichloromethane, $C{H}_{2}C{l}_2$ has a molecular dipole moment. Explain why and draw $C{H}_{2}C{l}_2$ in a way that demonstrates the molecular dipole. If you have a molecular model kit, build this molecule to help understand. If you don't, then use this online tool. After closing the popup window, click the trash can to clear, then click on $"C"$ and click in the screen, then click on the single bond in the upper left and click on the C twice, then click on $"$Cl$"$ and click on each bond coming off the central C$.$ Then, click $"2$D to $3$D$".$ Now, you can click on the $3$D structure and drag it around to look at it from all angles.
