1 Sec$on 10.1 Intermolecular Forces Chapter 11 Liquids and Intermolecular Forces

2 Sec$on 10.1 Intermolecular Forces Intramolecular Bonding Within the molecule. Molecules are formed by sharing electrons between the atoms. Copyright Cengage Learning. All rights reserved 2

3 Sec$on 10.1 Intermolecular Forces Intermolecular Forces

4 Sec$on 10.1 Intermolecular Forces Intermolecular Forces Forces that occur between molecules. Dipole dipole forces Ø Hydrogen bonding London dispersion forces Intramolecular bonds are stronger than intermolecular forces. Copyright Cengage Learning. All rights reserved 4

5 Sec$on 10.1 Intermolecular Forces Hydrogen Bonding in Water Blue dojed lines are the intermolecular forces between the water molecules.

6 Sec$on 10.1 Intermolecular Forces Phase Changes When a substance changes from solid to liquid to gas, the molecules remain intact. The changes in state are due to changes in the forces among molecules rather than in those within the molecules. Copyright Cengage Learning. All rights reserved 6

7 Sec$on 10.1 Intermolecular Schema$c Representa$ons Forces of the Three States of MaJer Copyright Cengage Learning. All rights reserved 7

8 Sec$on 10.1 Intermolecular Phase Changes Forces Solid to Liquid As energy is added, the mo$ons of the molecules increase, and they eventually achieve the greater movement and disorder characteris$c of a liquid. Liquid to Gas As more energy is added, the gaseous state is eventually reached, with the individual molecules far apart and interac$ng rela$vely lijle. Copyright Cengage Learning.

10 Sec$on 10.1 Intermolecular Forces Dipole-Dipole Forces Dipole moment molecules with polar bonds oven behave in an electric field as if they had a center of posi$ve charge and a center of nega$ve charge. Molecules with dipole moments can ajract each other electrosta$cally. They line up so that the posi$ve and nega$ve ends are close to each other. Only about 1% as strong as covalent or ionic bonds.

11 Sec$on 10.1 Intermolecular Dipole-Dipole Forces Orientation of Polar Molecules in a Solid

12 Sec$on 10.1 Intermolecular Forces Hydrogen Bonding The hydrogen bond is a special dipole-dipole interaction between the hydrogen atom in a polar N-H, O-H, or F-H bond and an electronegative O, N, or F atom. Copyright Cengage Learning. All rights reserved

13 Sec$on 10.1 Intermolecular Forces Hydrogen Bonding Strong dipole-dipole forces. Hydrogen is bound to a highly electronega$ve atom nitrogen, oxygen, or fluorine. That same hydrogen is then electrosta$cally ajracted to a lone pair on the nitrogen, oxygen or fluorine on adjacent molecules. Copyright Cengage Learning. All rights reserved 13

14 Sec$on 10.1 Intermolecular London Dispersion Forces Forces Instantaneous dipole that occurs accidentally in a given atom induces a similar dipole in a neighboring atom. Significant in large atoms/molecules. Occurs in all molecules, including nonpolar ones. Copyright Cengage Learning. All rights reserved 14

15 Sec$on 10.1 Intermolecular Forces Mel$ng and Boiling Points In general, the stronger the intermolecular forces, the higher the mel$ng and boiling points. Copyright Cengage Learning. All rights reserved 15

16 Sec$on 10.1 Intermolecular Boiling Points of Forces the Covalent Hydrides of the Elements in Groups 4A, 5A, 6A, and 7A Copyright Cengage Learning. All rights reserved 16

17 Sec$on 10.1 Intermolecular Forces The Liquid State

18 Sec$on 10.2 The Liquid State Liquids Low compressibility, lack of rigidity, and high density compared with gases. Surface tension resistance of a liquid to an increase in its surface area: Liquids with large intermolecular forces tend to have high surface tensions. Copyright Cengage Learning. All rights reserved 18

19 Sec$on 10.2 The Liquid State Liquids Capillary ac$on spontaneous rising of a liquid in a narrow tube: Cohesive forces intermolecular forces among the molecules of the liquid. Adhesive forces forces between the liquid molecules and their container. Copyright Cengage Learning. All rights reserved 19

20 Sec$on 10.2 The Convex Liquid Meniscus State Formed by Nonpolar Liquid Mercury Which force dominates alongside the glass tube cohesive or adhesive forces? cohesive forces Copyright Cengage Learning. All rights reserved 20

22 Sec$on 10.2 The Liquid State Liquids Viscosity measure of a liquid s resistance to flow: Liquids with large intermolecular forces or molecular complexity tend to be highly viscous. Copyright Cengage Learning. All rights reserved 22

25 Sec$on 10.8 Vapor Pressure and Changes of State Vapor Pressure Pressure of the vapor present at equilibrium. The system is at equilibrium when no net change occurs in the amount of liquid or vapor because the two opposite processes exactly balance each other. Copyright Cengage Learning.

26 Sec$on 10.8 Vapor Pressure and Changes of State Copyright Cengage Learning. All rights reserved 26

27 Sec$on 10.8 Vapor Pressure and Changes of State Vapor Pressure Liquids in which the intermolecular forces are large have rela$vely low vapor pressures. Vapor pressure increases significantly with temperature. Copyright Cengage Learning. All rights reserved 27
