1) 2-metylbutan
2) Từ \(CH_3-CH_2-CH\left(CH_3\right)-CH\left(C_2H_5\right)-CH_3\) ta bẻ mạch thành
\(CH_3-CH_2-CH\left(CH_3\right)-CH\left(CH_3\right)-CH_2-CH_3\)
2,3-đimetylhexan
3) 2,2-đimetylbutan
4) Từ \(CH_3-CHBr-CH_2-CH\left(C_2H_5\right)-CH_3\) bẻ mạch ta được:
\(CH_3-CHBr-CH_2-CH\left(CH_3\right)-CH_2-CH_3\)
2-brom-4-metylhexan
