1)
CH4+Cl2⇒CH3Cl+HCl
CH3Cl+2Na+ClCH3⇒CH3-CH3 + 2NaCl
CH3-CH3+Br2 ⇒ CH3-CH2Br + HBr
CH3-CH2Br + NH3 ⇒ CH3-CH2-NH2 + HBr
2CH3-CH2-NH2 + H2SO4 ⇒ (CH3-CH2-NH3)2SO4
(CH3-CH2-NH3)2SO4 + 2NaOH ⇒ 2CH3-CH2-NH2 + 2H2O+Na2SO4
CH3-CH2-NH2 + O=N-OH ⇒ CH3CH2OH + N2↑ + H2O
2)
2KCl =электролиз⇒ 2K + Cl2↑
2K + I2 = 2KI
2KI + Cl2 = 2KCl + I2↓
2K+H2O = 2KOH + H2↑
KOH + H2SO4 = KHSO4 + H2O
KHSO4 + KOH = K2SO4 + H2O
K2SO4+BaCl2 = BaSO4↓+2KCl
KCl + AgNO3 = AgCl↓ + KNO3
