纵观近几年的高考,有机化学一直是重要考察内容之一.众所周知,高考化学试题结构简单来说就是7+4,即7个选择和4个大题,其中有机化学一般都占2个选择(12分),后面最后一个大题选修(二选一)中,有机化学就占其一(15分),而2012年高考新课标理综卷化学中,还有一道实验题(14分)考察溴苯的制备,使整个100分卷面中,有机化学竟占了41分之多,由此可见,高考化学中,有机化学是不能忽视的一部分.其中,
Throughout the entrance examination in recent years, organic chemistry has always been one of the important content of the study.As we all know, the structure of the college entrance examination chemistry test is simple 7 + 4, that is, seven choices and four major problems, including organic chemistry generally account for two (12 points), followed by the last major elective (two choose one), organic chemistry accounted for one (15 points), and in 2012 the new college entrance examination physics comprehensive roll chemistry, there is an experiment (14 Points) to examine the preparation of bromobenzene, so that the entire 100 min surface, the organic chemistry actually accounted for as much as 41 points, we can see that the chemical entrance examination, organic chemistry can not be ignored as part of which,
