Answer 1

9.
a) C2H5OH + CuO = CH3CHO + Cu + H2O
б) 2C2H5OH + O2 = 2CH3CHO + 2H2O

10.
1) CH4 + Cl2 = CH3Cl + HCl
2) CH3Cl + KOH = CH3OH + KCl
3) 2CH3OH + O2 = 2HCHO + 2H2O
4) 2HCHO + O2 = 2HCOOH
5) 2HCOOH + Mg = (HCOO)2Mg + H2

11.
1) CH3COOH + C4H9OH = CH3COOC4H9 + H2O
2) HCOOH + C2H5OH = HCOOC2H5 + H2O

Answer 2

11. а) CH3-COOH+CH3-CH2-CH2-CH2OH<=>(Н+,t)CH3-COOCH2-CH2-CH2-CH3+H2O
CH3-CH2-CH2-CH2-CH2-COOH
б) HCOOH+CH3-CH2OH<=>(H+,t)HCOOCH2CH3+H2O
CH3-CH2-COOH
