Question

An unknown organic compound 'X' reacts with sodium metal to release hydrogen gas. It does not react with $NaOH$ or $NaHCO_3$. 'X' gives an immediate turbidity with Lucas reagent. What is 'X'?

Prashant Kotian · Accepted Answer

Correct answer: C. Reaction with Na confirms an acidic proton (alcohol/phenol). Failure to react with rules out phenol, confirming an aliphatic alcohol. Immediate turbidity with Lucas reagent strictly points to a highly reactive tertiary alcohol, such as 2-methylpropan-2-ol.
