For most of us, work is the central, dominating fact of life. We spend more than half our conscious hours at work, preparing for work, traveling to and from work. What we do there largely determines our standard of living and our status to a considerable extent. It is sometimes said that because leisure has become more important, the injustices of work can be pushed into a corner, and that because most work is pretty intolerable, the people who do it should compensate for its boredom, frustrations and humiliations by concentrating their hopes on the other parts of their lives. For the foreseea（1）分子式为C5Hl2O并能与金属钠反应放出H2的有机化合物有________种；（2）下列说法错误的是_____________；A.有机物均易燃烧B.苯酚酸性比碳酸弱，故苯酚不能与碳酸钠溶液反应C.制取乙酸乙酯时，试剂的混合顺序是先加浓硫酸，再加乙醇，然后加乙酸D.石油分馏得到的汽油是纯净物（3）分子式为C5H9C1O2的同分异构体甚多，其中能与NaHCO3发生反应产生CO2的同分异构体共有________种；（4）分子式为C3H6O2的链状有机物，核磁共振氢谱上峰的数目及强度比分别为:①3∶3；②3∶2∶1;③3∶1∶1∶1;④2∶2∶1∶1，则它们可能的结构简式依次为：①_______________；②______________；③_______________；④__________________。（5）苯氧乙酸（）有多种酯类的同分异构体，其中能与FeCl3溶液发生显色反应，且苯环上有2种一硝基取代物的同分异构体是_______________（写出任意2种的结构简式）（6）按系统命名法，右图化合物的名称是___________
