Помогите пожалуйста

Answer 1

Объяснение:

а) C2H4O + H2 = C2H6O

C2H6O + NaBr = C2H5Br +NaOH

C2H5Br (t) = C2H4 + HBr

C2H4 + H2O (H2SO4) = C2H6O

C2H6O (Ag, t) = C2H4O + H2

б) CH2O + H2 = CH4O

CH4O + NaCl = CH3Cl +NaOH

2CH3Cl + 2Na = C2H6 + 2NaCl

C2H6 + Cl2 (hv) = C2H5 +HCl

C2H5Cl + NaOH (р-р) = C2H6O + NaCl

C2H6O (Ag, t) = C2H4O +H2

2C2H4O + O2 = 2C2H4O2
