Write the reaction equation: methane-acetylene-benzene-nitrobenzene

Let’s write down the equations for organic substances:
2CH4 = C2H2 + 3H2 – decomposition of methane occurs when heated, acetylene is formed;
3С2Н2 = С6Н6 – the reaction of benzene trimerization proceeds on a hot carbon catalyst, benzene is released;
С6Н6 + HO – NO3 – C6H5NO2 + H2O – nitration of benzene is carried out with the participation of concentrated sulfuric acid as a dehydrating agent; nitrobenzene is obtained.
Reactions confirming the chain of transformations indicate a bond between alkanes, alkynes and aromatic hydrocarbons. Nitrobenzene, the end product of the conversion chain, is used in the production of aniline.
