Which one of the following properties is exhibited by phenol ?

Options

A. It is soluble in aq NaOH and evolves `CO_(2)` with aq `NaHCO_(3)`
B. It is soluble in aq NaOH and does not evolve `CO_(2)` with aq `NaHCO_(3)`
C. It is not soluble in aq NaOH but evolves `CO_(2)` with aq `NaHCO_(3)`
D. It is insoluble in aq NaOH but does not evolve `CO_(2)` with aq `NaHCO_(3)`

Answer

B

Explanation

Phenol is a weak acid. It reacts with `NaOH` to produce salt.
`C_(6)H_(5)OH+NaOH rarr underset("Sodium phenoxide")(C_(6)H_(5)overset(-)ON overset(+)a)+H_(2)O`
But it is not sufficiently acidic to evolve `CO_(2)` from `NaHCO_(3)` solution.
