The correct Answer is:
To analyze the statements provided in the question, we will evaluate each statement step by step. ### Step 1: Evaluate Statement 1 **Statement 1:** Alcohols cannot be dried by CaCl₂. - **Explanation:** Drying agents are substances that remove water from other substances. In the case of alcohols (which have the general formula R-OH), when they come into contact with CaCl₂ (calcium chloride), a reaction occurs. Calcium chloride can react with the alcohol to form calcium alkoxide (Ca(OR)₂) and release HCl. This reaction indicates that instead of drying the alcohol, CaCl₂ reacts with it, thus making it ineffective for drying alcohols. ### Step 2: Evaluate Statement 2 **Statement 2:** CaCl₂ forms solvated molecules with alcohols. - **Explanation:** When CaCl₂ interacts with alcohols, it forms calcium alkoxide (Ca(OR)₂). In this context, "solvated" means that the calcium ion (Ca²⁺) is surrounded by the alkoxide groups (R-O⁻) from the alcohol. This formation of solvated molecules indicates that CaCl₂ does indeed interact with alcohols, leading to the formation of these complexes. ### Conclusion - **Statement 1 is true:** Alcohols cannot be dried by CaCl₂ because they react to form calcium alkoxide. - **Statement 2 is true:** CaCl₂ does form solvated molecules with alcohols, specifically calcium alkoxide. ### Final Answer Both statements are true, and Statement 2 correctly explains Statement 1.
