Question

CH4-C2H2-C2H4-C2H6-C

Answer 1

СН4(стрелка вправо , над стрелкой t>1500C, под стрелкой быстрое) CH(тройное равно-тройная связь )СН+ 3Н2

CH(тройное равно)СН+Н2(стрелка вправо, над стрелкой t,Ni )СН2(двойная связь- или равно)СН2

СН2(двойная связь - или равно)СН2+H2(стрелка вправо, над стрелкой t,Ni )СН3-СН3

Answer 2

It seems like you've provided a sequence of chemical compounds: CH4, C2H2, C2H4, C2H6, and C. Each of these represents a different hydrocarbon molecule with varying numbers of carbon and hydrogen atoms.

1. CH4: Methane - This is the simplest hydrocarbon, consisting of one carbon atom and four hydrogen atoms. It's a colorless and odorless gas and is the main component of natural gas.

2. C2H2: Ethyne (also known as acetylene) - This hydrocarbon consists of two carbon atoms and two hydrogen atoms. It's a highly flammable gas and is commonly used in oxyacetylene welding and cutting torches.

3. C2H4: Ethene - This hydrocarbon has two carbon atoms and four hydrogen atoms. It's an important industrial chemical and is used in the production of plastics and various organic compounds.

4. C2H6: Ethane - This hydrocarbon has two carbon atoms and six hydrogen atoms. It's a component of natural gas and is used as a fuel for heating and cooking.

5. C: Carbon - In this context, "C" represents a single carbon atom. Carbon is the fundamental building block of organic molecules and is a key element for life as we know it.
