**Question:** Which of the following pairs contain the same intermolecular forces? - NH₃ and CH₄ - H₂S and CH₄ - CH₃CH₂OH and H₂O - CH₃Cl and H₂O *Explanation:* Intermolecular forces are the forces that mediate interaction between molecules. They influence properties like boiling points and solubilities. 1. **NH₃ and CH₄:** Ammonia (NH₃) exhibits hydrogen bonding due to the presence of nitrogen and hydrogen. Methane (CH₄) only displays dispersion forces as it is non-polar. 2. **H₂S and CH₄:** Hydrogen sulfide (H₂S) has dipole-dipole interactions along with dispersion forces, while methane (CH₄) only has dispersion forces. 3. **CH₃CH₂OH and H₂O:** Ethanol (CH₃CH₂OH) and water (H₂O) can both form hydrogen bonds, which is the predominant force in their interactions. 4. **CH₃Cl and H₂O:** Chloromethane (CH₃Cl) has dipole-dipole interactions due to its polar bond, whereas water (H₂O) primarily displays hydrogen bonding.
