Given below are two statements :

Statement I: Picric acid is 2, 4, 6-trinitrotoluene.
Statement II : Phenol-2, 4-disulphuric acid is treated with conc. to get picric acid.

In the light of the above statement, choose the most appropriate answer from the options given below :
  1. (A)Statement I is incorrect but Statement II is correct.✓ Correct
  2. (B)Both Statement I and Statement II are incorrect.
  3. (C)Statement I is correct but Statement II is incorrect.
  4. (D)Both Statement I and Statement II are correct.

Answer: (A)

Solution

Statement I is incorrect: picric acid is 2,4,6-trinitrophenol, not 2,4,6-trinitrotoluene.
Statement II is correct: phenol is sulphonated to phenol-2,4-disulphonic acid, which on treatment with conc. gives picric acid.
Hence Statement I is incorrect but Statement II is correct.
