某烯烃与H2加成后的产物是CH3-CH(CH3)-CH(CH3)-C(CH3)3,则该烯烃的结构可能有:答案是三种,为什么?
问题描述:
某烯烃与H2加成后的产物是CH3-CH(CH3)-CH(CH3)-C(CH3)3,则该烯烃的结构可能有:
答案是三种,为什么?
答
CH2=C(CH3)-CH(CH3)-C(CH3)3
CH3-C(CH3)=C(CH3)-C(CH3)3
CH3-CH(CH3)-C=H2
|
C(CH3)3
答
①CH2=C(CH3)-CH(CH3)-C(CH3)3②CH3-C(CH3)=C(CH3)-C(CH3)3③CH3-CH(CH3)=C(CH2)-C(CH3)3双键发生加那成
答
主要你没说一个烯烃分子和几个H2分子加成!!!两种情况
①.一个烯烃分子+一个H2 :两个结果
1.CH2=C(CH3)-CH(CH3)-C(CH3)3
2.CH3-C(CH3)=C(CH3)-C(CH3)3
②.一个烯烃分子+两个H2 :一个结果
3.CH2=C(CH3)C(CH3)=CH2
就是三种,你说对吗!!
答
1.CH2=C(CH3)-CH(CH3)-C(CH3)3
2.CH3-C(CH3)=C(CH3)-C(CH3)3
3.CH3-CH(CH3)-C(C(CH3))=CH2
答
1、CH2=C(CH3)-CH(CH3)-C(CH3)3
2、CH3-C(CH3)=C(CH3)-C(CH3)3
3、CH3-CH(CH3)-C=CH2

C(CH3)3
