Answer 1

Насчет того, что правильно не гарантирую. Такой вариант C2H6+Cl2=C2H5Cl C2H5Cl-HCl=C2H4(дегалогенирование) C2H4+H2=C2H6

Answer 2

Chemical Equation and Chain Structure

To solve the given chemical equation CnH2n+2(a)⇒?⇒CnH2n⇒CnH2n+2(a), we need to understand the chain structure and the reactions involved.

The given chemical equation represents the general formula for alkanes, which are hydrocarbons consisting of single-bonded carbon and hydrogen atoms. The general formula for alkanes is CnH2n+2, where "n" represents the number of carbon atoms in the molecule.

Chain Structure and Reactions

1. CnH2n+2 to CnH2n: The first step in the reaction involves the removal of two hydrogen atoms from the alkane molecule, resulting in the formation of an alkene. This process is known as dehydrogenation.

2. CnH2n to CnH2n+2(a): The second step involves the addition of two hydrogen atoms to the alkene molecule, resulting in the formation of an alkane. This process is known as hydrogenation.

Solution

The complete chain of reactions to solve the given equation is as follows: CnH2n+2(a)⇒CnH2n⇒CnH2n+2(a)

This represents the dehydrogenation of the alkane to form an alkene, followed by the hydrogenation of the alkene to form the original alkane.

This chain of reactions demonstrates the interconversion between alkanes and alkenes through dehydrogenation and hydrogenation processes.
