The correct Answer is:
To analyze the statements provided in the question, we will evaluate each statement separately and then determine their truthfulness. ### Step-by-Step Solution: 1. **Evaluate Statement 1: "CuO is called black oxide of copper."** - **Explanation:** Copper oxide (CuO) is indeed known as black oxide of copper. It is formed when copper reacts with oxygen, and it appears black in color. This statement is true. 2. **Evaluate Statement 2: "CuO is diamagnetic."** - **Explanation:** To determine if CuO is diamagnetic, we need to look at the oxidation state of copper in CuO. In CuO, copper is in the +2 oxidation state (Cu²⁺). The electronic configuration of copper (Cu) is [Ar] 3d¹⁰ 4s¹. When copper loses two electrons to form Cu²⁺, the configuration becomes [Ar] 3d⁹. The presence of unpaired electrons in the 3d subshell indicates that CuO is actually paramagnetic, not diamagnetic. Therefore, this statement is false. 3. **Conclusion:** - Statement 1 is true. - Statement 2 is false. Based on the evaluations: - **Final Answer:** The correct option is that Statement 1 is true and Statement 2 is false.
