Ответ:

1. 1) С + 2H2 =(Ni, t)=> CH4

2) CH4 + Br2 =(уф.)=> CH3Br + HBr

3) CH3Br + KOH =(водн.р-р, t)=> CH3OH + KBr

4) CH3OH + HCOOH => HCOOCH3 + H2O

2. 1) CH4 + Br2 =(уф.)=> CH3Br + HBr

2) 2CH3Br + 2Na => CH3-CH3 + 2NaBr

CH3-CH3 =(Pt,t)=> CH2=CH2 + H2

CH2=CH2 + H2O =(H3PO4, t)=> CH3-CH2OH

3) 5CH3CH2OH + 4KMnO4 + 6H2SO4 = 5CH3-COOH + 2K2SO4 + 4MnSO4 + 11H2O

4) CH3-COOH + Cl2 =(P кр.)=> CH2Cl-COOH + HCl
