Polarity and Intermolecular Forces

Master chemical polarity and intermolecular forces with this practice worksheet!

1. Bond Polarity Sort the following as polar bonds or nonpolar bonds. Refer to the electronegativity chart below. Polar Bond O-Cl C-Cl C-P Nonpolar Bond S-Br C-S Cl-Cl Ionic KCl KBr Ba-F B-F 2. Bond Polarity Arrange the bonds in order of increasing polarity (#1 being the least polar). Refer to the electronegativity chart on p. 9 of your notes. C-F 2 O-F 1 Be-F 3 3. Intermolecular Force v. Intramolecular Force On the picture below, label intramolecular or intermolecular force in each box. Intramolecular Intermolecular 4. Intermolecular Force Which is the most likely melting point and volatility of each substance? What type of bond is present?
