提问时间：2020-08-02

答案

CH3CH=CH2 + Cl2 (550度）=== CH2=CH-CH2Cl
CH2=CH-CH2Cl +H2 +Pd/H2 ===CH3-CH2-CH2Cl
CH2=CH-CH2Cl + Mg === CH2=CH-CH2MgCl
CH2=CH-CH2MgCl + CH3-CH2-CH2Cl + CuBr === CH2=CH-CH2CH2CH2CH3
CH2=CH-CH2CH2CH2CH3 + Br2 ===CH2BrCHBr-CH2CH2CH2CH3
CH2BrCHBr-CH2CH2CH2CH3 + NaOH === HC≡CCH2CH2CH2CH3(1-己炔)
CH3CH=CH2 + Br2 === CH3CHCBr-CH2Br
CH3CHBr-CH2Br + NaOH === CH3C≡CH
CH3C≡CH + BH3 + H2O2 + NaOH === CH3CH2CHO (丙醛）
CH2=CH-CH2MgCl + CH3CH2CHO === CH3CH2CH(OH)CH2CH2CH3
CH3CH2CH(OH)CH2CH2CH3 + H2SO4 === CH3CH2CH=CHCH2CH3 (脱水）
CH3CH2CH=CHCH2CH3 + Br2 === CH3CH2CHBrCHBrCH2CH3
CH3CH2CHBrCHBrCH2CH3 + NaOH ===CH3CH2C≡CHCH2CH3 (3-己炔)
其中应该有不同的异构体.
