    M:Hello,everyone.My name is Daniel.I’m glad to be your teacher of the course—Environmental Science.I’ll be guiding you through this exciting and important subject this term. To begin with,please take a look at the course schedule in front of you. This course is scheduled for Mondays and Wednesdays from 2:00 to 3:30 in the afternoon.Our lectures will take place in this classroom for the first half of the course,but we will have field trips every other week on Wednesdays during the last two months of the course to conduct hands-on research.Your grades will be determined by your performance in the midterm and final exams,classroom tests,and most importantly,your participation in class discussions.You’re encouraged to make use of my office hours,which are scheduled for Thursdays from 10:00 to 12:00.Additionally,you can arrange to meet with me at other times.Since the textbooks won’t arrive until this Friday,you can refer to my slides prepared for you.Now,class begins.

    【答案】 B
    【解析】 p轨道与p轨道能形成σ键,如Cl2中两个氯原子之间的σ键,是p-p σ键,故A错误;σ键为轴对称,可以绕键轴旋转,π键为镜面对称,不能绕键轴旋转,故B正确;BF3中含有B—F,属于极性共价键,BF3中B的价层电子对数为3+=3,其空间结构为平面正三角形,故C错误;乙烯中碳碳双键的键能比乙烷中碳碳单键的键能的2倍小,故D错误。
    2.下列对分子性质的解释不正确的是(  )
    [A] CS2结构与CO2相似,CS2难溶于水
    [B] 氯气易溶于NaOH溶液是因为“相似相溶”
    [C] 一个乳酸()分子中含有一个手性碳原子
    [D] 碘易溶于四氯化碳,甲烷难溶于水都可用“相似相溶”规律解释


    ii.配制溶液
    ①先向烧杯中加入 ,再缓慢加入 ,用玻璃棒缓慢搅动,使其混合均匀。
    ② 将烧杯中的溶液沿玻璃棒注入容量瓶。
    ③用少量蒸馏水洗涤烧杯内壁和玻璃棒2—3次,并将洗涤液也都注入容量瓶。
    ④继续向容量瓶中加入蒸馏水,直到液面在刻度线以下1—2cm时,改用胶头滴管滴加蒸馏水,至液面与刻度线相切。盖好容量瓶瓶塞,反复上下颠倒摇匀。
    (3)将配制好的0.5mol/L的稀硫酸溶液倒入指定的容器中。
