Question

CH4-CH3Br-C2H6-C2H4-C2H4

Answer 1

CH4 + Br2 = CH3Br + HBr

2CH3Br + 2Na = C2H6 + 2NaBr

C2H6 = C2H4 + H2

Если правильно поняла.

Answer 2

The sequence "CH4-CH3Br-C2H6-C2H4-C2H4" seems to represent a series of organic compounds connected by dashes. Each component appears to be a molecular formula or abbreviation for a specific compound. Let's break down each part:

1. CH4: This is the molecular formula for methane, which is the simplest hydrocarbon consisting of one carbon atom and four hydrogen atoms.

2. CH3Br: This represents methyl bromide, a halogenated organic compound consisting of a methyl group (CH3) and a bromine atom (Br).

3. C2H6: This is the molecular formula for ethane, a hydrocarbon with two carbon atoms and six hydrogen atoms.

4. C2H4: This is the molecular formula for ethene (ethylene), an unsaturated hydrocarbon with two carbon atoms and four hydrogen atoms. It contains a double bond between the two carbon atoms.

5. C2H4: This is again ethene (ethylene), the same compound as mentioned before.

The sequence seems to represent a series of compounds transitioning from simpler to more complex structures, including various hydrocarbons and halogenated compounds. Is there something specific you would like to know about this sequence of compounds?
