烃A1、A2互为同分异构体,它们各加1 mol H2都可得到烃B。A1、A2各加1 mo

烃A1、A2互为同分异构体,它们各加1 mol H2都可得到烃B。A1、A2各加1 mol HCl都得到C1。而B在光照下与氯气反应,只得到两种一氯代物C1和C2。其转化关系如下所示。B中碳的质量分数为83.7%。

则A1、A2、B和C1、C2的结构简式分别是:

A1_______,A2________,B________,C1_______,C2_________。

答案

(CH3)2CC(CH3)2   (A1、A2可互换)

(CH3)2CHCH(CH3)2    

解析:根据B中碳元素的质量分数为83.7%,可确定B为烷烃,A1、A2为烯烃,再结合其他条件,分别推出各物质的结构。
