The correct Answer is:
To solve the question, we need to analyze the two statements provided regarding the behavior of alcohols when they react with HX (where X is a halogen). ### Step-by-step Solution: 1. **Understanding the Reaction of Alcohols with HX**: - Alcohols (R-OH) react with hydrogen halides (HX) to form alkyl halides (R-X) and water (H2O). - The reaction can be represented as: \[ R-OH + HX \rightarrow R-X + H_2O \] - In this reaction, the hydroxyl group (OH) of the alcohol is replaced by the halogen (X), which is a substitution reaction. 2. **Analyzing Statement 1**: - Statement 1 claims that alcohols give only substitution products with HX and not elimination products. - Since the reaction of alcohols with HX results in the formation of alkyl halides and water, it confirms that the reaction is indeed a substitution reaction. - Therefore, **Statement 1 is true**. 3. **Understanding Elimination Reactions**: - Elimination reactions typically involve the removal of a small molecule (like water) and the formation of a double bond. - For an elimination reaction to occur, a strong base is usually required to abstract a proton (H+) from the alcohol. 4. **Analyzing Statement 2**: - Statement 2 states that X is a very weak base which cannot abstract a proton from alcohol. - Halogens (like Cl, Br, I) are indeed weak bases and do not have the ability to abstract protons effectively from alcohols. - Since X cannot abstract a proton, it cannot facilitate an elimination reaction. - Therefore, **Statement 2 is also true**. 5. **Conclusion**: - Since both statements are true and Statement 2 correctly explains why Statement 1 is true, we conclude that: - **Statement 1 is true**. - **Statement 2 is true**. - **Statement 2 is a correct explanation for Statement 1**. ### Final Answer: The correct option is: - Statement 1 is true, Statement 2 is true, and Statement 2 is a correct explanation for Statement 1. ---
