How to use these flashcards

Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: What is the VSEPR shape of $\text{BF}_3$?

Answer: Trigonal planar. Three bonding groups arrange in flat triangle.

Flashcard 2: Which has stronger intermolecular forces: $\text{H}_2\text{O}$ or $\text{CO}_2$?

Answer: $\text{H}_2\text{O}$. Water has hydrogen bonding vs. CO₂'s weak dispersion forces.

Flashcard 3: What type of bond is present in $\text{H}_2\text{O}$?

Answer: Polar covalent bond. O is more electronegative than H, creating unequal sharing.

Flashcard 4: Which has stronger intermolecular forces: $\text{H}_2\text{O}$ or $\text{CO}_2$?

Answer: $\text{H}_2\text{O}$. Water has hydrogen bonding vs. CO₂'s weak dispersion forces.

Flashcard 5: What type of bond is present in $\text{H}_2\text{O}$?

Answer: Polar covalent bond. O is more electronegative than H, creating unequal sharing.

Flashcard 6: What is the VSEPR shape of $\text{BF}_3$?

Answer: Trigonal planar. Three bonding groups arrange in flat triangle.

Flashcard 7: Which has stronger intermolecular forces: $\text{H}_2\text{O}$ or $\text{CO}_2$?

Answer: $\text{H}_2\text{O}$. Water has hydrogen bonding vs. CO₂'s weak dispersion forces.

Flashcard 8: What type of bond is present in $\text{H}_2\text{O}$?

Flashcard 9: What is the VSEPR shape of $\text{BF}_3$?

Answer: Trigonal planar. Three bonding groups arrange in flat triangle.

Flashcard 10: What is the primary intermolecular force in $\text{C}_2\text{H}_5\text{OH}$?

Answer: Hydrogen bonding. O-H bond enables hydrogen bonding with other molecules.

Flashcard 11: Which is stronger: hydrogen bond or van der Waals forces?

Answer: Hydrogen bond. Hydrogen bonds are stronger than dispersion forces.

Flashcard 12: Which interaction can occur between a polar molecule and an ion?

Answer: Ion-dipole interaction. Charge attracts to opposite partial charge on molecule.

Flashcard 13: Which has stronger intermolecular forces: $\text{HCl}$ or $\text{Ar}$?

Answer: $\text{HCl}$. HCl has dipole-dipole forces vs. Ar's dispersion only.

Flashcard 14: Which molecule has a higher boiling point: $\text{H}_2\text{O}$ or $\text{H}_2\text{S}$?

Answer: $\text{H}_2\text{O}$. Hydrogen bonding in water vs. weaker forces in H₂S.

Flashcard 15: Which has a higher boiling point: $\text{CH}_3\text{OH}$ or $\text{CH}_4$?

Answer: $\text{CH}_3\text{OH}$. Methanol has hydrogen bonding unlike nonpolar methane.

Flashcard 16: State the type of bond formed by the sharing of electron pairs.

Answer: Covalent bond. Electrons are shared between atoms in overlapping orbitals.

Flashcard 17: Identify the weakest type of intermolecular force.

Answer: London dispersion forces. Temporary induced dipoles provide minimal attraction.

Flashcard 18: What type of bond forms between $\text{H}$ and $\text{Cl}$ in $\text{HCl}$?

Answer: Polar covalent bond. Chlorine is more electronegative, creating unequal sharing.

Flashcard 19: Identify the strongest type of interparticle force present in water.

Answer: Hydrogen bonding. H bonded to O creates strong dipole-dipole interactions.

Flashcard 20: Name the type of bond formed between metals and nonmetals.

Answer: Ionic bond. Metal cations and nonmetal anions attract electrostatically.

Flashcard 21: Which bond is stronger: single, double, or triple covalent bond?

Answer: Triple covalent bond. More shared electrons create stronger, shorter bonds.

Flashcard 22: Which force is primarily responsible for the high boiling point of water?

Answer: Hydrogen bonding. H-O bonds create strong intermolecular attractions.

Flashcard 23: What type of interaction occurs between nonpolar molecules?

Answer: London dispersion forces. Temporary dipoles induce attractions in all molecules.

Flashcard 24: What is the term for the attraction between molecules of the same substance?

Answer: Cohesion. Intermolecular forces between identical molecules.

Flashcard 25: What is the primary intermolecular force in $\text{CH}_4$?

Answer: London dispersion forces. Nonpolar methane only exhibits weak temporary dipole forces.

Flashcard 26: Identify the type of force that holds $\text{Na}^+$ and $\text{Cl}^-$ together.

Answer: Ionic bond. Electrostatic attraction between oppositely charged ions.

Flashcard 27: Which type of bond involves the transfer of electrons?

Answer: Ionic bond. Complete electron transfer from metal to nonmetal occurs.

Flashcard 28: What is the bond type in a molecule with a large difference in electronegativity?

Answer: Ionic bond. Electronegativity difference > 1.7 typically results in electron transfer.

Flashcard 29: What is the strongest type of intramolecular force?

Answer: Covalent bond. Shared electrons create the strongest molecular attractions.

Flashcard 30: Identify the type of bond in diatomic oxygen ($\text{O}_2$).

Answer: Double covalent bond. Two pairs of electrons are shared between oxygen atoms.
