B

- Hướng dẫn giải

Phương pháp giải:

Giải chi tiết:

\((C{H_2} = C{H_2})\xrightarrow{{ + {H_2}O/xt}}{\mkern 1mu} C{H_3}C{H_2}OH(X)\xrightarrow{{xt,{t^0}}}C{H_2} = CH - CH = C{H_2}(Y)\xrightarrow{{xt\,Na\,,{t^0}}}{\mkern 1mu} ( - C{H_2} - CH = CH - C{H_2} - )po\lim e{\mkern 1mu} M.\)

\(C{H_2} = C{H_2} + {H_2}O\xrightarrow{{{H^ + },{t^0}}}C{H_3}C{H_2}OH\)

\(2C{H_3}C{H_2}OH\xrightarrow{{A{l_2}{O_3},C{r_2}{O_3},{{450}^0}C}}C{H_2} = CH - CH = C{H_2} + 2{H_2}O + {H_2}\)

\(nC{H_2} = CH - CH = C{H_2}\xrightarrow[{Na}]{{xt,{t^0},p}}\underbrace {{{( - C{H_2} - CH = CH - C{H_2} - )}_n}}_{poli\,butadien}\)
