Determine the oxidation state of carbon and write down the structural formulas of the following substances, knowing that carbon in organic compounds is always tetravalent: methane CH4, carbon tetrachloride CCL4, ethane C2H4, acetylene C2H2.

Let us determine the oxidation state of the following compounds: methane CH4, carbon tetrachloride CCL4, ethene C2H4, acetylene C2H2.
СН4 – oxidation state of carbon – 4, hydrogen + 1.
CCl4 – carbon oxidation state – 4, chlorine oxidation state – 1.
С2Н4 – oxidation state of carbon – 2, hydrogen + 1.
С2Н2 – oxidation state of carbon – 1, hydrogen + 1.
Structural formula of methane.
