An unknown alcohol is treated with the ‘Lucas reagent' to determine whether the alcohol is primary, secondary or tertiary. Which alcohol reacts fastest and by what mechanism?

(JEE Main 2013)

Detailed Solution for Retro (Past 13 Year)JEE Main (Alcohols Phenols And Ethers) - Question 2

The reaction of alcohol with Lucas reagent is mostly SN1 reaction and the rate of reaction is directly proportional to the stability of carbocation formed in the reaction.
Since, 3° R—OH forms 3° carbocation (most stable) hence, it will react fastest by SN1 reaction.
