A compound 'X' is acidic and it is soluble in NaOH solution, but insoluble in solution. Compound 'X' also gives violet colour with neutral solution. The compound 'X' is:
  1. (A)(see structure)
  2. (B)(see structure)
    ✓ Correct
  3. (C)(see structure)
  4. (D)(see structure)

Answer: (B)

Solution

Compound X is phenol. Phenols are weakly acidic and soluble in strong bases like NaOH but not in weak bases like (unlike carboxylic acids which dissolve in both). The violet color with neutral is a characteristic test for phenols, confirming the presence of the phenolic -OH group. Cyclohexanol and benzyl alcohol do not give this test.
