Câu 1:

\(\left(-C_6H_{10}O_5-\right)_n+nH_2O\xrightarrow[^{t^o}]{^{Axit}}nC_6H_{12}O_6\)

\(C_6H_{12}O_6\xrightarrow[^{30~35^oC}]{^{men.ruoi}}2CO_2+2C_2H_5OH\)

\(2C_2H_5OH\underrightarrow{^{t^{o,Al2O3}}}CH_2=CH-CH=CH_2+H_2+H_2O\)

\(nCH_2=CH-CH=CH_2\xrightarrow[^{xt}]{^{t^o,p}}\left(-CH_2-CH=CH-CH_2-\right)_n\)

Câu 2:

\(CH_2=CH-CH=CH_2+2H_2\xrightarrow[^{Ni}]{^{t^o}}CH_3-CH_2-CH_2-CH_3\)

\(CH_2=CH-CH=CH_2+HBr\left[{}\begin{matrix}CH_2Br-CH=CH-CH_3\\\left[{}\begin{matrix}CH_3-CHBr-CH=CH_2\\CH_2Br-CH_2-CH=CH_2\end{matrix}\right.\end{matrix}\right.\)

\(CH_2=CH-CH=CH_2+Br_2\left[{}\begin{matrix}CH_2Br-C=CH-CH_2Br\\\left[{}\begin{matrix}CH_2Br-CBr-CH=CH_2\\CH_2=C-CHBr-CH_2Br\end{matrix}\right.\end{matrix}\right.\)
