A compound 'X' is acidic and it is soluble in NaOH solution, but insoluble in

NaHCO X_{3}

solution. Compound 'X' also gives violet colour with neutral

FeCl X_{3}

solution. The compound 'X' is:

Answer: (B)

Compound X is phenol. Phenols are weakly acidic and soluble in strong bases like NaOH but not in weak bases like

NaHCO X_{3}

(unlike carboxylic acids which dissolve in both). The violet color with neutral

FeCl X_{3}

is a characteristic test for phenols, confirming the presence of the phenolic -OH group. Cyclohexanol and benzyl alcohol do not give this test.
