The correct Answer is:
To solve the question, we need to evaluate the two statements provided: **Statement 1:** 1,1-Dichloroethane on treatment with aqueous KOH yields ethanol. **Statement 2:** Ethylene dichloride is an unsaturated compound. ### Step-by-step Solution: 1. **Analyze Statement 1:** - 1,1-Dichloroethane has the formula CH3CHCl2. - When treated with aqueous KOH, the hydroxide ions (OH⁻) will attack the carbon atoms bonded to chlorine. - Since there are two chlorine atoms attached to the same carbon (geminal dihalide), both chlorines can be replaced by hydroxyl groups (OH). - The reaction can be represented as: \[ CH3CHCl2 + 2 KOH \rightarrow CH3C(OH)2 + 2 KCl \] - The product formed is a diol (CH3C(OH)2), which is unstable due to the presence of two hydroxyl groups on the same carbon. - This diol will undergo dehydration (loss of water) to form ethanal (acetaldehyde, CH3CHO): \[ CH3C(OH)2 \rightarrow CH3CHO + H2O \] - Thus, Statement 1 is **True**. 2. **Analyze Statement 2:** - Ethylene dichloride (1,2-dichloroethane) has the formula CH2Cl-CH2Cl. - To determine if it is saturated or unsaturated, we check for the presence of double or triple bonds between carbon atoms. - In ethylene dichloride, there are only single bonds between the carbon atoms (C-C), indicating that it is a saturated compound. - Therefore, Statement 2 is **False**. ### Conclusion: - Statement 1 is True. - Statement 2 is False. The correct option is **C: Statement 1 is True, Statement 2 is False.** ---
