Hoàn thành câu hỏi sau

a: CH2=CH2+HBr ——>

b: CH2=CH-CH3 + HCL ——>

c: CH2=CH-CH3 + H2 —NI t。—>

d: C2H5OH —H2SO4 đặc 170 độC ——>

Giải chi tiết giúp mình nhé

Cảm ơn ạ

Các phản ứng xảy ra:

\(C{H_2} = C{H_2} + HB{\text{r}}\xrightarrow{{}}C{H_3} - C{H_2}B{\text{r}}\)

\(C{H_2} = CH - C{H_3} + HCl\xrightarrow{{}}C{H_3} - CHCl - C{H_3}\)

\(C{H_2} = CH - C{H_3} + {H_2}\xrightarrow{{Ni,{t^o}}}C{H_3} - C{H_2} - C{H_3}\)

\({C_2}{H_5}OH\xrightarrow{{{H_2}S{O_4},{{170}^o}C}}C{H_2} = C{H_2} + {H_2}O\)

$CH_2=CH_2+HBr\to CH_2Br-CH_3$

$CH_2=CH-CH_3+HCl\to CH_3-CHCl-CH_3$

$CH_2=CH-CH_3+H_2\xrightarrow{t^o,Ni}CH_3-CH_2-CH_3$

 $C_2H_5OH\xrightarrow{170^oC,H_2SO_4}C_2H_4+H_2O$
