Question

CH4→C2H2→C6H6→CLC6H6

Answer 1

2CH4 (1500°)= C2H2 + 3H2

3C2H2 (t,p,C) = C6H6

C6H6 + 3Cl2 (hv)= C6H6Cl6

Answer 2

The chemical equation you provided appears to show a series of reactions involving different molecules. Let's break it down step by step:

1. CH4 → C2H2: This reaction represents the transformation of methane (CH4) into acetylene (C2H2). The balanced chemical equation for this reaction is: CH4 → C2H2

2. C2H2 → C6H6: This reaction shows the conversion of acetylene (C2H2) into benzene (C6H6). The balanced chemical equation for this reaction is: 2 C2H2 → C6H6

3. C6H6 → CLC6H6: This reaction seems to involve the substitution of a hydrogen atom in benzene (C6H6) with a chlorine atom (Cl), resulting in chlorobenzene (C6H5Cl). The balanced chemical equation for this reaction is: C6H6 + Cl2 → C6H5Cl + HCl

Putting it all together, the entire sequence of reactions would look like this: CH4 → C2H2 2 C2H2 → C6H6 C6H6 + Cl2 → C6H5Cl + HCl

If there are specific conditions or catalysts involved, they should be stated along with the reactions to provide a comprehensive picture of the chemical process.
