Ch3br=c2h4=c2h5oh=ch3coh=ch3cooh

Question

Ch3br=c2h4=c2h5oh=ch3coh=ch3cooh

Answer 1

2CH3Br+2Na------>CH3-CH3+2NaBr;
CH3-CH3-(t,Pt)---->CH2=CH2+H2; (в одну стадию не смог этилен(C2H4) получить)
CH2=CH2+H2O --(кисл.)-----> CH3-CH2-OH;
CH3-CH2-OH+CuO------>CH3-COH+Cu+H2O;
CH3-COH+2Cu(OH)2------>Cu2O+CH3-COOH+2H2O
