Question

CH3-CHO->CH2-OH->CH3-CH2-Br->C2H4->CH3-CH2-OH->CH3-CHO->CH3-COOH->CH3-COONa Решите пожалуйста!

Answer 1

1) с2h4o+ h2= c2h5oh
2)c2h5oh+hBr= c2h5br+h2o
3) c2h5br+KOH(cпирт,р-р)= с2h4+h2o+Kbr
4)c2h4+ H2o=c2h5OH
5)c2h5oh+ CuO=c2h4o+Cu+H2o
6)c2h4o+Cu(oh)2= Cu2o+H2o+c2h4o2
7)c2h4o2+Naoh= Ch3-COONa+ H2o
