Read the description of dipole-dipole forces on page 9 of your lab manual. polar molecules experience permanent partial positive and partial negative charges. use arrows (like the ones shown on page 9 of your manual) to show the direction of the net dipoles in the following molecules. if there is no net dipole, circle the molecule (18 pts). hint: when drawing your arrows, think about electronegativity of each atom. the arrow will point towards the location of the electron density. the first one is done for you.
