Осуществите преобразование в цепочке ch4→ch3cl→c2h6→c2h5br→c2h5oh→c2h4→c2h2→ch3coh

1. CH4 + Cl2 = CH3Cl + HCl

2. 2CH3Cl + 2Na = 2NaCl + C2H6

3. C2H6 + Br2 = C2H5Br + HBr

4. C2H5Br + KOH = C2H5OH + KBr

5. C2H5OH = C2H4 + H2O ( дегидратация )

6. C2H4 (t)= C2H2 + H2 ( дегидрирование )

7. C2H2 + H2O ( соли Hg(+2) ) = CH3COH.
