JEE Main · 2024 · 08 Apr 2024 · Shift 2 · Alcohols Phenols and Ethers

Which one the following compounds will readily react with dilute NaOH ?

(A) $C_{6} H_{5} CH_{2} OH$
(B) $C_{2} H_{5} OH$
(C) $(CH_{3})_{3} COH$
(D) $C_{6} H_{5} OH$ ✓ Correct

Answer: (D)

Solution

Phenol (

C_{6} H_{5} O H

) is acidic enough (its conjugate base, phenoxide, is resonance-stabilised) to react readily with dilute NaOH, forming sodium phenoxide and water. Benzyl alcohol, ethanol and tert-butanol are far weaker acids and do not react with dilute NaOH.
