Write the reaction equation: C2H6 -? – C4H10 -? – C4H8-C4H9OH

1. The reaction of chlorination (replacement of hydrogen with chlorine) with the formation of chloroethane. Flow conditions – chemically active light or catalyst: peroxides, iodine.
C2H6 + Cl2 = C2H5Cl + HCl.
2. The Wurtz reaction – an increase in the hydrocarbon chain under the action of metallic sodium with the formation of butane. Compound reaction.
C2H5Cl + 2Na + C2H5Cl = C4H10 + 2NaCl.
3. Chlorination (substitution) reaction at 250–400 ° С, catalyst. Obtaining chlorobutane.
C4H10 + Cl2 = C4H9Cl + HCl.
4. The reaction of exchange, the formation of butene in the presence of an alcoholic alkali solution.
C4H9Cl + KOH = C4H8 + KCl + H2O.
5. The addition reaction with the formation of butanol in the presence of nickel-cobalt catalysts at 1.0-1.5 MPa.
C4H8 + H2O = C4H9OH.
