合司秋环体转大对 Q:what is petrolum ether? Petroleum ether is obtained from petroleum refineries as the portion of the distillate which is intermediate between the lighter naphtha and the heavier kerosene._(movie) specific gravity of between 0.6 and 0.8 ■Remember .Petroleum ether should not be confused with the class of organic compounds called ethers,which contain the-O-functional group. Likewise,benzine should not be confused with benzene.Benzine is a mixture of alkanes,e.g., pentane,hexane,and heptane,whereas benzene is a cyclic,aromatic hydrocarbon,C6H6

Study Tips提示 Read the assigned textbook chapter before class. Write out the main notes and focus on what covered in class. Spend at least two to three hours studying out of class for every time spent in class. .This is a very minimal amount of time to spend on a course of this type.You will be rewarded for your efforts.Remember that you are competing with other students.Students that fail usually do so because they're too busy not because they're dumb or lazy. Be an active learner .Form a study group and be an active learner.Don't just memorize,but integrate the information into your existing knowledge base and emphasize understanding. ■提前预习/做课堂笔记/课后做一定量的题/勤思考，多交流，及 时整理 "Chance favors the prepared mind. ■答疑时间： ----Louis Pasteur
