- Tác dụng với clo khi chiếu ánh sáng là CH4 ; C2H6.
\(C{H_4} + C{l_2}\buildrel as \over\longrightarrow C{H_3}Cl + HCl\)
\({C_2}{H_6} + C{l_2}\buildrel as \over\longrightarrow {C_2}{H_5}Cl + HCl\)
- Làm mất màu dung dịch brom : CH2=CH2; CH2=CH-CH3.
\(C{H_2} = C{H_2};C{H_2} = CH - C{H_3}\)
\(C{H_2} = C{H_2} + B{r_2} \to C{H_2}Br - C{H_2}Br\)
\(C{H_2} = CH - C{H_3} + B{r_2} \to C{H_2}BrCHBr - C{H_3}\)
- Có phản ứng trùng hợp là CH2 = CH2 ; CH2 = CH - CH3.
\({n_{C{H_2}}} = C{H_2}\mathrel{\mathop{\kern0pt\longrightarrow}\limits_{p,{t^o}}^{xt}} - \left( {C{H_2} - C{H_2}} \right)\)
\({n_{C{H_2}}} = CH - C{H_3}\mathrel{\mathop{\kern0pt\longrightarrow}\limits_{p,{t^o}}^{xt}} - {\left( \matrix{C{H_2} - CH \hfill \cr \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,| \hfill \cr \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,C{H_3} \hfill \cr} \right)_n}\)
