The correct Answer is:
To determine which pairs exhibit dipole-induced dipole interactions, we need to analyze each option based on the nature of the molecules involved (polar or non-polar). ### Step-by-Step Solution: 1. **Understanding Dipole-Induced Dipole Interactions**: - Dipole-induced dipole interactions occur when a polar molecule induces a dipole in a non-polar molecule. This happens because the electric field of the polar molecule can distort the electron cloud of the non-polar molecule, creating a temporary dipole. 2. **Analyzing Each Pair**: - **Option 1: SiCl4 and Helium Atom**: - SiCl4 is a polar molecule, but helium is a noble gas and non-polar. However, SiCl4 is not a strong polar molecule that can induce a significant dipole in helium. Therefore, this pair does not exhibit dipole-induced dipole interactions. - **Option 2: Water and Alcohol**: - Both water and alcohol (like ethanol) are polar molecules. Dipole-induced dipole interactions are not relevant here as both are polar. Thus, this pair does not exhibit dipole-induced dipole interactions. - **Option 3: Chlorine Gas and Calcium Tetrachloride**: - Chlorine gas (Cl2) is non-polar, and calcium tetrachloride (CaCl2) is ionic. While ionic compounds can interact with non-polar molecules, the interaction here is not classified as dipole-induced dipole. Therefore, this pair does not exhibit dipole-induced dipole interactions. - **Option 4: Hydrochloric Acid and Helium Atom**: - Hydrochloric acid (HCl) is a polar molecule, and helium is a non-polar atom. In this case, HCl can induce a dipole in the helium atom, leading to dipole-induced dipole interactions. This pair exhibits the desired interaction. 3. **Conclusion**: - The correct answer is **Hydrochloric acid and helium atom** as this pair exhibits dipole-induced dipole interactions. ### Final Answer: The correct pair exhibiting dipole-induced dipole interactions is **Hydrochloric acid and helium atom**.
