Вещества CH2, C2H5, C2H2, C6H5, NO3, C6H5

- CH2: CH2 is the chemical formula for methylene, which is a highly reactive and unstable molecule. It consists of a carbon atom bonded to two hydrogen atoms. Methylene is often involved in chemical reactions and is used in various industrial processes.

- C2H5: C2H5 is the chemical formula for ethyl, which is an alkyl group derived from ethane. It consists of two carbon atoms bonded together with five hydrogen atoms attached to one of the carbon atoms. Ethyl is commonly found in organic compounds and is used in the production of solvents, fuels, and other chemicals.

- C2H2: C2H2 is the chemical formula for acetylene, which is a highly flammable gas. It consists of two carbon atoms bonded together with two hydrogen atoms attached to each carbon atom. Acetylene is used in welding and cutting torches, as well as in the production of various chemicals.

- C6H5: C6H5 is the chemical formula for phenyl, which is a benzene ring without any substituents. It consists of six carbon atoms arranged in a hexagonal ring with alternating single and double bonds. Phenyl is often used as a functional group in organic chemistry and is found in many aromatic compounds.

- NO3: NO3 is the chemical formula for the nitrate ion, which is a polyatomic ion composed of one nitrogen atom bonded to three oxygen atoms. The nitrate ion is commonly found in fertilizers and is involved in various chemical reactions.

- C6H5: C6H5 is the chemical formula for phenyl, as mentioned earlier. It represents a benzene ring without any substituents.
