Question

C2H6-C2H4-C2H2-C6H6​

Answer 1

Ответ:

Объяснение:

CH3-CH3  ->  CH2=CH2 + H2  (t, kat)

CH2=CH2  ->  CH=-CH  + H2 (t,kat)

3CH=-CH -> C6H6  (C, t)

Answer 2

The sequence "C2H6-C2H4-C2H2-C6H6" represents a series of hydrocarbons, which are compounds composed of hydrogen and carbon atoms. Let's break down each compound in the sequence:

1. C2H6: This is ethane, a saturated hydrocarbon with two carbon atoms and six hydrogen atoms. Its chemical formula is CH3-CH3.

2. C2H4: This is ethene, an unsaturated hydrocarbon with two carbon atoms and four hydrogen atoms. It has a double bond between the two carbon atoms and is commonly used in the production of plastics.

3. C2H2: This is ethyne, also known as acetylene. It has two carbon atoms and two hydrogen atoms and contains a triple bond between the carbon atoms. Acetylene is often used in welding and as a starting material for the synthesis of various organic compounds.

4. C6H6: This is benzene, a cyclic aromatic hydrocarbon with six carbon atoms and six hydrogen atoms. It has a unique structure involving alternating single and double bonds and is a fundamental building block in organic chemistry.

The sequence you provided represents a progression from saturated hydrocarbons (ethane) to unsaturated hydrocarbons (ethene) and further to a triple-bonded hydrocarbon (ethyne), and finally to an aromatic hydrocarbon (benzene). This sequence showcases the structural diversity that carbon atoms can exhibit in hydrocarbon compounds.
