a) \(CH_3-CH_2-C\left(CH_3\right)_2-CH\left(C_2H_5\right)-CH_2-CH_3\)
b) \(CH_2Br-CHCl-CH\left(CH_3\right)-CH_2-CH_3\)
c) \(CH_2Cl-CCl\left(CH_3\right)-CH_2-CH_2-CH_2-CH_3\)
d) \(CH_3-CH\left(CH_3\right)-CH_2-CH_3\)
\(CH_2=C\left(CH_3\right)-CH_2-CH_3\\ CH_2-CH-C\left(CH_3\right)\left(CH_3\right)-CH_3\\ CH_2=CH-CH\left(CH_3\right)-CH_2-CH_3\\ CH_3-CH=C\left(CH_3\right)-CH_2-CH_3\\ CH_3-CH=C\left(CH_3\right)-CH_3\\ CH_3-C\left(CH_3\right)=C\left(CH_3\right)-CH_3\\ CH_3-C\left(CH_3\right)=C\left(CH_2-CH_3\right)-CHCl-CH_3\\ CH_2=CH-CH=CH_2\\ CH_2=C\left(CH_3\right)-CBr=CH_2\)
Viết CTCT các chất sau ( kể cả đồng phân hình học ) a) pent -2-en b) 2-metylbut-1-en c) 2-metylpent-2-en d) 2-clo-3-metylpent-2-en e) 3-metylhex-2-en g) 2,3-di

\(Câu3:\)
\(CT:C_nH_{2n+2}\)
\(M_A=32\cdot2.25=72\left(\dfrac{g}{mol}\right)\)
\(\Rightarrow14n+2=72\)
\(\Rightarrow n=5\)
\(CT:C_5H_{12}\)
\(C_5H_{12}\) có 3 đồng phân
\(CH_3-CH_2-CH_2-CH_2-CH_3\)
\(CH_3-CH\left(CH_3\right)-CH_2-CH_3\)
\(\left(CH_3\right)_4C\)
Vì : sản phẩm thế là 2 - clo - 2metylbutan
nên A là : đồng phân thứ hai
