Hydrogen bonding between water molecules. H bonding is responsible for many of the important properties of water such as high cohesion, surface tension, boiling point and its role as a universal solvent.
This would be a great bonding lesson transitioning from lewis dot structures. After students realize where the unpaired electrons are they can model bonding using this activity. This would also beautifully model double and triple bonds. Students can redraw these models in their notebooks. Physical Science Activities
This PowerPoint presentation cover the three main types of bonds: covalent, ionic, and hydrogen bonds. Bond symbols and their meanings are also included. Examples of single, double, and triple bonds are given along with descriptions of these bonds. Ionic bonding and the characteristics of an ionic bond are discussed; an animation further adds to the description.
This video describes major intermolecular forces discussed in chapter 11. Dipole-dipole forces increase in strength with increasing polarity. London dispersion forces increase in strength with increasing molecular weight. Hydrogen bonding occurs in compounds containing O-H, N-H, and F-H bonds. Hydrogen bonds are generally stronger than dipole-dipole and dispersion forces. This video clearly summarized and clarified my knowledge of intermolecular forces.
