1. _____________ bonding type is characterized by the transfer of electrons from one atom to another. A. Ionic B. Covalent C. Metallic D. Van der Waals Correct answer: A. Ionic Rationale: In ionic bonding, electrons are transferred from one atom to another, resulting in the creation of positively and negatively charged ions. 2. True or False: A molecule that is polar will dissolve in a nonpolar solvent. Correct answer: False Rationale: Molecules that are polar will dissolve in polar solvents, while nonpolar molecules will dissolve in nonpolar solvents. 3. When a substance undergoes distillation, which of the following is true? A. It is sepa into its individual components by freezing B. It is sepa into its individual components by boiling C. It is sepa into its individual components by filtration D. It is sepa into its individual components by crystallization Correct answer: B. It is sepa into its individual components by boiling Rationale: Distillation involves heating a mixture to separate its components based on their different boiling points. 4. Which spectroscopy technique involves measuring the absorption of infrared radiation by a sample? A. UV-Vis spectroscopy B. NMR spectroscopy C. IR spectroscopy
