Question

Which of the following compounds has the most acidic nature?

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

Phenol is most acidic of all the given compounds.

Among the given compounds, in Phenol, the electron withdrawing phenyl ring polarizes the $\text{O}-\text{H}$ bond thereby facilitating the release of $\text{H}$ as ${\text{H}}^{+}$ and hence phenol is most acidic.
