When does a solution of two liquids, A and B, behave most like an ideal solution in term of vapor pressure. (a) When the interactions between molecules of the two different components (A and B) are the same as the interactions between molecules of each individual component. (b) When the interactions between molecules of the two different components (A and B) are stronger than the interactions between molecules of each individual component. (c) When the interactions between molecules of the...

A solution is called "ideal" when: choose one: a. the forces of attraction between solute and solvent molecules are somewhat smaller than between solute-solute molecules or solvent-solvent molecules. b. the forces of attraction between solvent molecules exceed those between solute and solvent molecules. c. the forces of attraction between solute molecules exceed those between solute and solvent molecules. d. all intermolecular forces of attraction are the same, resulting in no net enthalpy change when the solution is formed from its...

9. A mixture (solution) of 3 different liquid compounds is formed. Each compound has the same condensed formula of C4H10O. Separate analyses of these compounds confirmed that none of the compounds has branching of C’s from the main chain of attached C atoms. Also one of the compounds experiences a weaker interparticle force as its dominant force than the other two. (a) Draw 3 possible preferred Lewis structures consistent with the above formula and information. It is desired to separate...

INTERMOLECULAR FORCES INTRODUCTION LEARNING OBJECTIVES To relate the effecet of intermolecular forces on relative melting points and vapour pressures of some organic substances THEORY Weak attractive forces that occur between individual molecules in substances are called intermolecular forces. These include London dispersion forces, dipole-dipole forces and hydrogen-bonding forces. Collectively, the three types of intermolecular forces are referred to as Van der Waals forces. These attractive forces are much weaker than the chemical bonds between atoms in a molecule. Note that...
