簡單化學題反應方程式

C2H6(g)+Br2(l)---->C2H5Br(g)+HBr(g) orange gas
C2H5Br(g)+Br2(l)--->C2H4Br2(g)+HBr(g)
C2H4Br2(g)+Br2(l)--->C2H3Br3(g)+HBr(g)
If you continue to add the ecessive bromine to ethane the reaction will be stopped
until the ethane has become the haxbromoethaneC2Br6
this type of reaction called substituent reaction
乙烷+酸化高錳酸鉀好似係無反應
烯+酸化高錳酸鉀先會有

注意異構體.
C2H4Br2 是有兩個可能的結構:
　　Ｈ　Ｈ
　　｜　｜
Br－Ｃ－Ｃ－Br
　　｜　｜
　　Ｈ　Ｈ

　　Ｈ　Br
　　｜　｜
Ｈ－Ｃ－Ｃ－Br
　　｜　｜　
　　Ｈ　Ｈ
