1、CH=CH-CH2CH3+HCl→ 2、H3C-CH2CH2-COOH +稀碱→ 3、HC3-CH2-COOH+H3C-OH H2SO4→还有H2=C -CH3 +KMnO4/H+ →- CH3

1 CH=CH-CH2CH3+HCl→CH3－CH2Cl-CH2CH3（加成反应）
2、H3C-CH2CH2-COOH +稀碱→ H3C-CH2CH2-COONa+H2O(中和反应)
3、HC3-CH2-COOH+H3C-OH H2SO4→HC3-CH2-COO－CH3+2H2O（成酯反应）
4 还有 H2C = CH2 +KMnO4/H+ → CH3 - CH3(氧化反应)
注;最后4是否你写错了分子式.应为上式“H2C = CH2”
