（12分）经测定乙醇的化学式是C2H6O，由于有机物普遍存在同分异构现象，推测乙醇的结构可能是下列两种之一。
为测定其结构，应利用物质的特殊性进行定性、定量实验。现给出乙醇、钠、水及必要的仪器，请甲、乙两位同学直接利用如图给定装置开始进行实验确定乙醇的结构。
（1）学生甲得到一组实验数据如上表：
| 乙醇的物质的量/mol | 氢气的体积/L |
| 0.10 | 1.12（标准状况） |
根据以上数据推断乙醇的结构为 （用Ⅰ、Ⅱ表示），理由为
，
该反应的化学方程式为： 。
（2）同学乙分别准确称量4.60 g乙醇进行多次实验，结果发现以排在量筒内水的体积作为生成的H2体积，换算成标准状况后都小于1.12L，如果忽略量筒本身及乙同学读数造成的误差，那么乙认为可能是由于样品中含有少量水造成的，你认为正确吗？ （填“正确”或“不正确”）。请说明你判断的理由 。
（3）实验后，两名同学从乙醇的可能结构分析入手，对乙醇和钠的量的关系进行了讨论，如果乙醇的物质的量为n mol，那么对钠的物质的量的取值要求必须是 n（填“大于”、“小于”或“等于”）。
