Molecular and Ionic Bonding
What kind of intramolecular force exists between two chlorine atoms in a Cl₂ molecule?
Hydrogen bond
Covalent bond
Ionic bond
Dipole-dipole interaction
As the temperature increases for a sample of neon gas, what happens to the potential energy associated with its atoms?
The potential energy decreases as kinetic energy decreases.
The potential energy increases due to higher kinetic energy.
The potential energy turns into chemical energy as bonds form.
The potential energy remains constant because neon is inert.
When does attraction occur?
Charges are the same
Charges are increasing
Electrons are not transferred
Charges are opposite
Which experimental question is most likely to yield significant insights about the role of molecular geometry in determining the strength of London dispersion forces?
What is the effect of molar mass on the solubility of ionic compounds?
How does varying temperature impact the color intensity in a complex ion solution?
How does changing the length of hydrocarbon chains affect their boiling points?
Does altering the pH level influence reaction rates in enzyme-catalyzed reactions?
How does solvent polarity affect solubility of a compound?
Nonpolar solvents increase solubility regardless of compound polarity due to their low affinity for other molecules.
Solvent polarity is not related to solubility; only temperature affects whether or not something dissolves.
Like dissolves like, indicating polar solvents best dissolve polar compounds, whereas nonpolar solvents dissolve nonpolar compounds.
Polar solvents cause ion-dipole interactions which always lead to decreased solubility.
How does increasing the temperature affect the rate of a chemical reaction in which all reactants are gases?
It decreases the reaction rate by reducing the number of effective collisions between gas particles.
It decreases the potential energy difference between reactants and products, slowing down the reaction.
It increases the reaction rate by causing the gas particles to move more rapidly and collide more frequently.
It has no effect on the reaction rate but increases the potential energy of the products compared to reactants.
What is true about equilibrium bond length?
Potential energy is likely over 0
Occurs when bond energy is higher
It is the distance at which atoms are least stable
It is the distance between atoms when potential energy is at its lowest point

Which factor accounts for ethane (C₂H₆) having lower potential energy at room temperature than ethanol (C₂H₅OH)?
Ethanol exhibits greater covalent bond strengths within its molecular structure.
Ethane has a larger molecular size leading to smaller surface area interactions.
Ethane demonstrates increased polarizability over ethanol contributing more effectively towards potential energy.
Ethanol has stronger intermolecular hydrogen bonds requiring more energy.
Which of the following best describes the relationship between the boiling point of a substance and its intermolecular forces?
The boiling point is independent of intermolecular forces.
The weaker the intermolecular forces, the higher the boiling point.
The boiling point decreases exponentially with stronger intermolecular forces.
The stronger the intermolecular forces, the higher the boiling point.
