- Q1Which of the following is NOT a general type of intermolecular force?Dipole-dipole interactionsIonic bondHydrogen bondingLondon dispersion forces30s
- Q2What is the effect of intermolecular forces on the boiling point of a substance?Only affects solidsLower boiling pointNo effect on boiling pointHigher boiling point30s
- Q3What is the relationship between the polarity of a molecule and its solubility in polar solvents?Generally insolubleGenerally solubleNo effect on solubilityOnly soluble in nonpolar solvents30s
- Q4Which of the following intermolecular forces is the strongest?Hydrogen bondingVan der Waals forcesLondon dispersion forcesDipole-dipole interactions30s
- Q5Which of the following statements is true about determining if a molecule is polar or non-polar?If the molecule has non-polar bonds, it is always non-polar.If the molecule has polar bonds and the molecular geometry is asymmetrical, it is polar.The molecular geometry of a molecule has no influence on its polarity.All molecules with polar bonds are polar regardless of molecular geometry.Polarity cannot be determined based on bond type or molecular geometry.30s
- Q6Which of the following elements was synthesized in the laboratory based on the concept of atomic number?OxygenTechnetiumCarbonIron30s
- Q7Which intermolecular force is responsible for the unique properties of water, such as high boiling point and surface tension?Dipole-dipole interactionsVan der Waals forcesHydrogen bondingLondon dispersion forces30s
- Q8Which of the following intermolecular forces is present in all molecules?Van der Waals forcesHydrogen bondingLondon dispersion forcesDipole-dipole interactions30s
- Q9Which of the following statements accurately describes the relationship between intermolecular forces and the properties of substances?Higher melting and boiling points indicate weaker intermolecular forces.Intermolecular forces have no effect on the melting and boiling points of substances.Stronger intermolecular forces result in higher melting and boiling points.Weaker intermolecular forces result in higher melting and boiling points.30s
- Q10Which concept led to the synthesis of new elements in the laboratory?Atomic massAtomic numberChemical formulaMolar mass30s
- Q11How can you determine if a molecule is polar or non-polar given its structure?By checking the melting point of the moleculeBy examining the molecule's symmetry and polarity of its bondsBy analyzing the molecular weightBy counting the number of atoms in the molecule30s
- Q12What is the atomic number of carbon?2681030s
- Q13What is the general trend for atomic number across periods in the periodic table?Decreases from left to rightIncreases from left to rightRemains constantVaries randomly30s
- Q14What is the valence electron configuration of oxygen?2s2 2p41s2 2s2 2p62s1 2p52s2 2p230s
- Q15What is the process of combining two or more atoms to form a new substance called?Nuclear fusionPhysical changeChemical bondingPhase change30s
