Напишите уравнения реакций для осуществления превращений: c3h7oh -> ch3-ch2-coh -> ch3-ch2-cooh -> ch3-chci-cooh -> ch3-ch(nh2)-cooh -> ch3-ch(nh2)-coo-c3h7 : )

1.С3Н7ОН+СuO⇒Cu+C2H5CH=O
2.C2H5CH=O+Na2Cr2O7+H2SO4⇒C2H5COOH+Cr2O3+Na2SO4
3.CH3-CH2-COOH+Cl2⇒CH3-CHCl-COOH+HCl
4.CH3-CHCl-COOH+NH3⇒CH3-CH(NH2)-COOH+HCl
5.CH3-CH(NH2)-COOH+C3H7OH⇒CH3-CH(NH2)-COOC3H7+H2O
