QUIZ 1. Benzene is what type of solvent? a. Polar and participatory b. Nonpolar and participatory c. Polar and non-participatory d. Nonpolar and non-participatory Answer: d. Benzene is a nonpolar molecule because there are no major dipole moments. It does not add anything to the reactions, making it a non-participatory molecule. 2. Acetic acid is what type of solvent? a. Polar and participatory b. Nonpolar and participatory c. Polar and non-participatory d. Nonpolar and non-participatory Answer: a. Acetic acid is a polar molecule that is also an acid, making it a participatory molecule in the reactions that take place within it. 3. The dielectric constant will determine the polarity of a solvent. What is the “cutoff” for a nonpolar versus polar solvent? a. 1 b. 3 c. 5 d. 20 Answer: c. A dielectric constant of 5 or less is considered a nonpolar solvent.
