a, 
b, Buta-1,3-đien và isopren đều là ankađien nên có nhiều tính chất hoá học giống nhau.
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:
\(CH_2=CH-CH=CH_2+2H_2\xrightarrow[^{Ni}]{^{t^o}}CH_3-CH_2-CH_2-CH_3\)
\(CH_2=CH-CH=CH_2+HBr\left[{}\begin{matrix}CH_2Br-CH=CH-CH_3\\\left[{}\begin{matrix}CH_3-CHBr-CH=CH_2\\CH_2Br-CH_2-CH=CH_2\end{matrix}\right.\end{matrix}\right.\)
\(CH_2=CH-CH=CH_2+Br_2\left[{}\begin{matrix}CH_2Br-C=CH-CH_2Br\\\left[{}\begin{matrix}CH_2Br-CBr-CH=CH_2\\CH_2=C-CHBr-CH_2Br\end{matrix}\right.\end{matrix}\right.\)
\(nCH_2=CH_2\rightarrow\left(-CH_2-CH_2-\right)_n\)
\(CH_4\underrightarrow{^{H2,1400oC}}C_2H_2\rightarrow H_2C=CH-C\equiv CH\underrightarrow{^{+H2}}H_2C=\)
\(CH-CH=CH_2\underrightarrow{^{to,xt}}-\left(-CH_2-CH=CH-CH_2-\right)_n-\)
Câu 1:
a. \(CH_2=CH-CH=CH_2+2H_2\underrightarrow{^{to,Ni}}CH_3-CH_2-CH_2-CH_3\)
b. \(CH_2=CH-CH=CH_2+Br_2\rightarrow Br-CH_2-CH\left(Br\right)-CH=CH_2\)
c. \(CH_2=CH-CH=CH_2+HBr\underrightarrow{^{40oC}}CH_3-CH=CH-CH_2-Br\)
d. \(CH_2=C\left(CH_3\right)-CH_2-CH_3+H_2\underrightarrow{^{Ni,to}}CH_3-C\left(CH_3\right)=CH-CH_3\)
e. \(CH_2=C\left(CH_3\right)-CH_2-CH_3+Br_2\rightarrow Br-CH_2-C\left(Br\right)\left(CH_3\right)-CH_2-CH_3\)
Câu 2:

\(CH\equiv C-CH_2-CH_3\) : but - 1 - in
\(CH_3-C\equiv C-CH_3\) : but - 2 -in
- C5H8
\(CH\equiv C-CH_2-CH_2-CH_3\) : pent - 1 - in
\(CH_3-C\equiv C-CH_2-CH_3\) : pent - 2 - in
\(CH\equiv C-CH\left(CH_3\right)-CH_3\) : 3 - metylbut - 1- in
