The Lucas test is utilized to differentiate classes of alcohols based on their reactivity kinetics w — Alcohols Phenols and Ethers Chemistry Question

💡 Solution & Explanation

Turbidity is caused by the insolubility of the resulting alkyl halide. Benzyl and allyl alcohols form highly resonance-stabilized carbocations, causing them to react very rapidly via an $S_N1$ mechanism, much like tertiary alcohols. Statement C is incorrect because tertiary alcohols react via an $S_N1$ mechanism (carbocation intermediate), not $S_N2$. Primary alcohols are too unreactive to form turbidity at room temperature.
