2 - metylpropen : \(CH_2=C\left(CH_3\right)_2\) hay \(C_4H_8\)
a, \(CH_2=C\left(CH_3\right)_2+Br_2\rightarrow CH_2Br-CBr\left(CH_3\right)_2\)
b,\(3C_4H_8+2KMnO_4+2H_2O\rightarrow3C_4H_8\left(OH\right)_2+4KOH+4MnO_2\)
c, \(CH_2=C\left(CH_3\right)_2+HCl\rightarrow CH_3-CCl\left(CH_3\right)_2\) ( Sản phẩm chính )
\(CH_2=C\left(CH_3\right)_2+HCl\rightarrow CH_2Cl+CH\left(CH_3\right)_2\) ( Sản phẩm phụ )
d, \(CH_2=C\left(CH_3\right)_2\underrightarrow{^{to,P}}-\left(CH_2-C\left(CH_3\right)_2\right)-n\)
