Draw the attraction between a water molecule and a molecule of NF3 First, draw one molecule and add the partial charges where needed - use the ΔEN to determine the types of bonds. Then, draw the second molecule so that the δ+ on one molecule lines up across from the δ- on the other. Since we can't draw the molecules here you will answer questions about the drawings that you made on the homework worksheet. NF3 has ____________ bonds with a ΔEN = ____________ . NF3 has 4 REDs and is symmetrical/asymmetrical (answer is ________ ) making it a polar/nonpolar (answer is __________ ) molecule. Each F has a ______________ charge and the N has a ________ charge. H2O has 2 ___________ bonds with a ΔEN = ___________ . H2O has 4 REDs and is symmetrical/asymmetrical (answer is ___________ . ) making it a polar/nonpolar (answer is _________ ) molecule. Each H has a _____________ charge and the O has a ____________ charge. The strongest possible attractive force between these two…
