Write the reaction equation: C – CH4 – C2H2 – C6H6 – CO2

Let’s implement the solution:
С + 2Н2 = СН4 – the reaction of the compound, methane was formed;
2CH4 = C2H2 + 3H2 – decomposition of methane, occurs at a high temperature with the participation of a catalyst, acetylene is released;
3C2H2 = C6H6 – trimerization is possible on hot coal, benzene is obtained;
2С6Н6 + 15О2 = 12СО2 + 6Н2О – combustion of benzene, smoky flame, carbon dioxide is released.
In the process of reactions, substances for practical purposes are formed, for example, methane, acetylene and benzene are involved in combustion reactions, and are used as fuel. The reactions show the connection between organic and inorganic substances.
