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 separated into its individual components by freezing
B. It is separated into its individual components by boiling
C. It is separated into its individual components by filtration
D. It is separated into its individual components by crystallization
Correct answer: B. It is separated 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
