Question

CH4→C2H2→C6H6→C6H5NO2→C6H5NH2

Answer 1

2CH4=C2H2+3H2
3C2H2=C6H6
C6H6+HNO3= C6H5NO2+H2O
C6H5NO2+H2=C6H5NH2

Answer 2

Chemical Reaction: CH4 → C2H2 → C6H6 → C6H5NO2 → C6H5NH2

The given chemical reaction involves a series of transformations starting from methane (CH4) and ending with aniline (C6H5NH2). Let's break down each step of the reaction:

1. CH4 → C2H2: - Methane (CH4) is converted into acetylene (C2H2). - The reaction occurs at a temperature of 1500°C. - The balanced equation for this reaction is: 2CH4 → C2H2 + 3H2.

2. C2H2 → C6H6: - Acetylene (C2H2) is further transformed into benzene (C6H6). - The specific conditions for this conversion are not provided in the given information.

3. C6H6 → C6H5NO2: - Benzene (C6H6) undergoes a reaction to form nitrobenzene (C6H5NO2). - The details of this reaction are not provided in the given information.

4. C6H5NO2 → C6H5NH2: - Nitrobenzene (C6H5NO2) is finally reduced to aniline (C6H5NH2). - The reduction process involves the removal of the nitro group (-NO2) and its replacement with an amino group (-NH2). - The specific conditions for this reduction reaction are not provided in the given information.

Please note that the details of the reactions between C2H2 → C6H6 and C6H5NO2 → C6H5NH2 are not mentioned in the provided information. Additional information or specific reaction conditions would be required to provide a more detailed explanation of these steps.
