Question

2-甲基-1.3丁二烯和溴化氢1:1加成方程式

Answer 1

CH2=C(CH3)CH=CH2+HBr →BrCH2-CH(CH3)-CH=CH2
CH2=C(CH3)CH=CH2+HBr →CH2=CH(CH3)-CHBrCH3
CH2=C(CH3)CH=CH2+HBr →BrCH2-C(CH3)=CHCH3
CH2=C(CH3)CH=CH2+HBr →CH3-C(CH3)=CHCH2Br
就这四种反应。

Answer 2

CH2=CCH3CH=CH2+HBR=BRCH2-CHCH3-CH=CH2

CH2=CCH3CH=CH2+HBR=CH2=CCH3-CH2-CH2BR

追问

还有吗？

追答

CH2=C(CH3)CH=CH2+HBr →CH2=CH(CH3)-CHBrCH3
CH2=C(CH3)CH=CH2+HBr →CH3-CBR(CH3)-CH=CH2
