Which of the following statements regarding the solution process is incorrect? Multiple Choice When a solution is formed from an ionic compound, the anions and cations are evenly distributed throughout the solution When a polar covalent compound dissolves in water, dipole-dipole interactions take place between the water molecules and the solute molecules. A nonpolar compound such as hexane, C6H14, forms London dispersion forces with a nonpolar solute, such as 12 during the solution process. O The solution process is always...

14. (3 pts.) The ionized benzoic acid dissolves better in water than it does in diethyl ether, which is how and why it is extracted into the water phase. Give the most important IMFs that are responsible for solubilizing the benzoic acid anion in the water. Give also the most important IMFs that are responsible for solubilizing the sodium cation in the water. The kinds of strong IMF that could be present are ion-dipole, hydrogen bonding (ignore dipole-dipole and induced...

2. Identify the strongest type of intermolecular forces in acetone, ethanol, water and hexane. (Structures listed on page 15.) Experiment 2 Intermolecular Forces There are three general types of intermolecular forces. All substances exhibit London Dispersion Forces (LDF), and they are generally the weakest of the three types. These London forces are due to the attractions between small, temporary dipoles that arise from the constant, random movement of the electrons in a substance. As molar mass increases, the size of...
