Make up the reaction equations: methane – acetylene – ethene – dichloroethane.

1) Acetylene can be obtained from methane at very high temperatures.

2) To obtain ethylene, it is necessary to hydrogenate acetylene. Lithium aluminum hydride (LiAlH4), sodium in liquid ammonia, diisobutyl aluminum hydride (DIBAL), hydrogen in the presence of Pd / CaCO3, Pb (2+) (Lindlar catalyst), hydrogen in the presence of Pd / BaSO4, quinoline (Rosenmund catalyst) …

3) The reaction of halogenation of ethylene with molecular chlorine (Cl2).
