9．解析：浓H2SO4会将氧化铜溶解，A错误；C2H5OH能与氧化铜反应：C2H5OH＋CuOCu＋CH3CHO＋H2O，B正确；CH3COOH会将氧化铜溶解，C错误；稀盐酸会将氧化铜溶解，D错误。
答案：B
10．解析：该物质分子式为C4H8O，A错误；该分子中含烷基，所有原子不可能共平面，B错误；该分子中含碳碳双键，能发生加成反应，烷基上含氢原子，还含有羟基，能发生取代反应，C正确；—OH也能使酸性高锰酸钾溶液褪色，不能用酸性KMnO4溶液检验该物质中的碳碳双键，D错误。
答案：C
11．解析：实验目的是乙醇的催化氧化，装置①的作用是制备氧气，装置②的作用是乙醇和氧气均匀混合，热水加热提供稳定的气流，装置③是乙醇、氧气在催化剂下发生反应，装置④吸收乙醛和未反应的乙醇。装置①的作用是制备氧气，MnO2作催化剂，装置③发生2CH3CH2OH＋2CH3CHO＋2H2O，氧气为氧化剂，故A说法错误；装置①的作用是制备氧气，反应2H2O22H2O＋O2↑，装置③发生2CH3CH2OH＋O22CH3CHO＋2H2O，两个反应都有O—H键的断裂，故B说法正确；金属网可以是铜制的，发生2Cu＋O22CuO、CH3CH2OH＋CuO―→CH3CHO＋Cu＋H2O，故C说法正确；乙醛、乙醇均能溶于水，因此装置④可充分吸收乙醛和少量的乙醇，并防止倒吸，故D说法正确。
答案：A
12．解析：CuSO4·5H2O不能再结合水，加入后无现象，故无法证明酒精中是否含水，A错误；由现象知，乙醇燃烧生成CO2和H2O，可以说明乙醇中含有C、H元素，但不能确定是否含有氧元素，B错误；由现象“铜丝能保持红热一段时间”，可以说明反应为放热反应，C正确；0.01 mol Na和过量乙醇生成标准状况下112 mL氢气，但因为乙醇过量，无法确定就是一个H与O相连，D错误。
