斯火会根据酸碱电子理论,Lewis碱是能提供电子对的物质(即电子给体)。下列物质不是Lewis碱的是()斯火会斯火会 A. (CH3)3C B. Cl- C. OH- D
指出下列化合物中,哪些是Lewis酸。(a)CH3OH (b) (CH3)3C+ (c) BF3 (d) AlCl3 (e)H+(f)Cl-A.aB.bC.cD.dE
答案解析 查看更多优质解析 解答一 举报 Lewis理论,也叫“电子理论” 定义:凡能提供电子对的物质叫碱,能从碱接受电子对的物质叫酸.酸+ 碱:= A:B (CH3)3COK中氧能提供孤对电子——[(CH3)3CO:]-,故为Lewis 碱 解析看不懂?免费查看同类题视频解析查看解答 ...
