Make the reaction equations: methane → A → benzene → B → diphenyl (C6H5-C6H5)

Let us write down the reaction equations that can be used to carry out these transformations:
1.2CH4 = 1500 ° C = C2H2 (A) + 3H2
2.3C2H2 = C (act) = C6H6
3.C6H6 + Cl2 = (FeCl3) = C6H5Cl (B) + HCl
4.2C6H5Cl + 2Na = C6H5-C6H5 + 2NaCl
