Assume that the two atoms are covalently bound to each other and to a larger molecule at the first dash symbol. Can the atom that is underlined (as shown) participate in a hydrogen bond with another atom from a different molecule? −O−H −C−H −N−H −O−H −C−H Can the oxygen of -O-H participate in a hydrogen bond? Can the hydrogen of -C-H participate in a hydrogen bond? Can the nitrogen of -N-H participate in a hydrogen bond? Can the hydrogen of O-H participate in a hydrogen bond? Can the carbon of -C-H participate in a hydrogen bond?arrow_forwardExplain the difference between a polar bond and a polar molecule.arrow_forward
- Use the VSEPR model to predict the bond angles around each central atom in the following Lewis structures (benzene rings are frequently pictured as hexagons, without the letter for the carbon atom at each vertex). Note that the drawings do not necessarily depict the bond angles correctly.arrow_forwardWhy do polar molecules have a greater tendency to remain a liquid or a solid at room temperature?arrow_forward
