【知识点】化学平衡单元测试
【答案】
A
2、 有两种有机物Q(
)与P(
),下列有关说法中正确的是( )
A. 二者的核磁共振氢谱中均只出现两种峰且峰面积之比为3∶2
B. 二者在NaOH醇溶液中均可发生消去反应
C. 一定条件下,二者在NaOH溶液中均可发生取代反应
D. Q的一氯代物只有1种、P的一溴代物有2种
【知识点】烃的衍生物单元测试
【答案】
【答案】C
【解析】试题分析：A．Q中两个甲基上有6个等效氢原子，苯环上有2个等效氢原子，峰面积之比应为3∶1，但是P 中两个甲基上有6个等效氢原子，亚甲基上有4个等效氢原子，峰面积之比应为3∶2，A项错误；B．苯环上的卤素原子无法发生消去反应，P中与卤素原子相连的碳原子的邻位碳原子上没有氢原子，无法发生消去反应，B项错误；C．在适当条件下，卤素原子均可被—OH取代，C项正确；D．Q中苯环上的氢原子、甲基上的氢原子均可被氯原子取代，可得到2种一氯代物，P中有两种不同空间位置的氢原子，P的一溴代物有2种，D项错误；答案选C。
考点：卤代烃的结构、性质。

4、Fifty–eight percent of the teachers interviewed in the Association of Teachers and Lecturers (ATL) questionnaire had come across copying among their pupils. Gill Bullen from Itchen College in Southampton, for example, said, "Pieces handed in by two students were identical and significantly better than either of them could have done. Not only that, the essays handed in didn't quite answer the title question I had set". A teacher from Leeds said, "I had one piece of work so bravely cut and pasted that it still contained ads from the web page."
Connie Robinson from Stockton Riverside College said, "With less able students it is easy to spot copying as the writing style changes in the middle of the assignment, but with more able students it is sometimes necessary for tutors to carry out Internet research to identify the source of the copy."
Mary Bousted, general secretary of the ATL, said," Teachers are struggling under a mountain of cut-and-pasting to spot whether work was the student's own or copy." She called for policies to stop copying, and asked for help from exam boards and the government in providing resources and techniques to detect cheats.
But there was another side. "I have found once students clearly understand what copying is, its consequences and how to reference correctly so they can draw on published works, copying becomes less of a problem," said Diana Baker from Emmanuel College, Durham.
"I think the majority of students who engage in copying do it more out of ignorance than the desire to cheat. They really want to succeed on their own."
