Redox reactions: Preparing Benzoic acid from toluene

Damien Leimbach  Follow
Can you know the difference between toluene and benzoic acid (benzoate ion)?

Your explanation is just a mess - in point 1 (i) you use the numbers 1, 2, 3, and in point 2 (ii) you use the numbers 1a, 1b, 1c.

Difference between Toluene(C6H5CH3) and benzoic acid(C6H5COOH).

 Benzoic acid is prepared by replacing 2 H⁺ atoms in CH3 molecule of toluene by 2 O-2 atoms.

1. Where is equation 3?
2. The error is evident
3. Correct the mistake in equation 1b, then there will be no problem.


In the second figure, you use inconsistent numbering. Should be 1a, 1b, 1a + 1b = 1, 2a, 2b, 2a + 2b = 2

1. Equation 3 is in(i) Acidic medium tagged 1+2=3.

2. Would you explain how can i rectify the error?

  In the second image, all the equations Tagging is self-explanatory.

now look at the reaction 2.

Reaction 2 must be [tex] C_6H_5CH_3 (l) + 2H_2O (l) \rightarrow  C_6H_5COOH (s) + 6H^+ (aq) + 6e^- \times 5 [/tex]

 Thanks for pointing out the error in reaction 2.

   In (i) Acidic medium, i understood how the equation 3 is derived.
  In (ii) Basic and neutral media also, I don't find any error.

The answer provided is correct in my opinion.
