A.NH4OH B.HCN C.H2O2 D.CCl4 答案 C [解析] (1)sP杂化 由1个s轨道和1个p轨道组合成2个sp杂化轨道。每个sp杂化轨道都含有[*]和[*]成分,两个等同sp杂化轨道简单夹角180°(呈直线形)。注意,除BeCl2外,周期表ⅡB族Zn、Cd、Hg元素的某些共价化合物(如ZnCl2、HgCl2、 CdCl2等),BeH2、CO2、CS2、C2...
This was confirmed through the study of COP width changes in NH4OH : H2O2 : H2O (SC-1) solution. The COP width depends on the rates of change in width and the shape of its void. The rates of change of width of the COP which originated from the lower portion of the void was found...
