Question

CH4 = > C2H2 > CH3OH > CH3CH2OH > CH3CH2Br>C2H4>CH3CH2OH>CH3COH>CH3COOH>CH3COONA

Answer 1

2CH4->t*= C2H2 + H2
C2H2 + H2O=CH3CHO
CH3CHO + H2 = CH3CH2OH
CH3-CH2OH+HBr=CH3-CH2Br+H2O 
CH3-CH2Br=C2H4+HBr
C2H4+H2O=CH3-CH2OH 
CH3COH + Ag2O = CH3COOH
Ch3Cooh + C2H5OH=Ch3coo-c2h5 + H2O
СH3COO-C2H5 + NaOH=CH3COONA + C2H5Oh

Chemical Reaction Sequence

The given chemical reaction sequence appears to depict a series of transformations starting with methane (CH4) and ending with sodium acetate (CH3COONA). Let's break down the transformations step by step:

1. CH4 -> C2H2 - The first transformation is from methane (CH4) to acetylene (C2H2).

2. C2H2 -> CH3OH - The next transformation is from acetylene (C2H2) to methanol (CH3OH).

3. CH3OH -> CH3CH2OH - Methanol (CH3OH) is then converted to ethanol (CH3CH2OH).

4. CH3CH2OH -> CH3CH2Br - Ethanol (CH3CH2OH) undergoes a transformation to form ethyl bromide (CH3CH2Br).

5. CH3CH2Br -> C2H4 - Ethyl bromide (CH3CH2Br) is then converted to ethylene (C2H4).

6. C2H4 -> CH3CH2OH - Ethylene (C2H4) is transformed back to ethanol (CH3CH2OH).

7. CH3CH2OH -> CH3COH - Ethanol (CH3CH2OH) undergoes a transformation to form acetaldehyde (CH3COH).

8. CH3COH -> CH3COOH - Acetaldehyde (CH3COH) is then converted to acetic acid (CH3COOH).

9. CH3COOH -> CH3COONA - Finally, acetic acid (CH3COOH) is transformed into sodium acetate (CH3COONA).

This sequence represents a series of chemical reactions where each compound is transformed into the next compound in the sequence.
