【解析】(I)硫和氯元素电负性强于磷元素，同一周期中，第ⅡA族、第VA族元素的原子轨道中电子处于全满或半满，较稳定，不易失电子，所以第ⅡA族、第VA族元素第一电离能大于其相邻元素，磷是第三周期第VA族元素，故其电离能大于硫元素；综上所述，同周期元素中第一电离能和电负性均大于磷元素的是氯元素。(2)①白磷(P4)分子为正四面体结构，其中P的杂化类型为sp;根据NaH2PO2可知，H3PO2中有一个可电离的H,其结构式为;等电子体是指价电子数和原子数（氢等轻原子不计在内）HOHH相同的分子、离子或原子团，与PH3互为等电子体的离子为HO十。②根据黑磷的结构，P一P的键长不完全相等，因此键能不完全相同，故A正确；石墨晶体层与层之间的作用力是分子间作用力，所以黑磷晶体层与层之间的作用力是分子间作用力，故B错误；石墨结构中六个碳原子形成正六边形，共面，由黑磷结构可知，六个磷原子形成的六元环不共面，因此黑磷分子中不存在大π键，故C错误。(3)由图可知，晶胞中磷原子空间堆积方式为面心立方堆积；已知该晶体的密度为pg·cm3,一个58×458X4晶驰中含有4个AP,设品驰边长为a,所以p侣-g·cm3,则a=NAcm,则最近的A1和P原子间的核间矩为×√XX10”m36.【化学一选修5：有机化学基础】(15分，除标注外，每空2分)《人民日报》推荐“新冠病毒感染者用药”之一为双氯酚酸钠缓释片(G),其一种合成路线如下：回答下列问题：(1)C→D的反应类型是还原反应。D>E的副产物是SO2和H2O(或H2SO3)。(2)D中含氧官能团的名称是羟基。理科综合试题第97页
