Question

Осуществить цепочки превращений. Химия 10 класс

Answer 1

Ответ:

1)C2H6 = C2H4 + H2

C2H4 + HCI = C2H4Cl2

C2H4Cl2 + 2KOH = C2H2 + 2KCl

3C2H2 = C6H6

2C6H6 + 15O2 = 12CO2 + 6H2O

2)C2H6 + Cl2 = C2H5Cl + HCl

2C2H5Cl + 2Na = C4H10 + 2NaCl

CH3CH2CH2CH3 = CH2=CHCH2CH3 + H2

CH2=CHCH2CH3 + HBr = CH3CH(Br) CH2CH3

3)C2H6 + Br2 = C2H5Br + HBr

2C2H5Br + 2Na = C4H10 + 2NaBr

C4H10 + Br2 = C4H9Br + HBr

C4H9Br + NaOH = C4H8 + NaBr + H2O
