JEE MAIN - Chemistry (2013 (Offline) - No. 10)

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:

tertiary alcohol by S_N1

secondary alcohol by S_N2

tertiary alcohol by S_N2

secondary alcohol by S_N1

Explanation

Tertiary alcohols reacts fastest with lucas reagnet as the rate of reaction is directly proportional to the stability of carbocation formed in the reaction. Since most stable $${3^ \circ }$$ carbocation is formed in the reaction hence it will react fastest further tetriary alcohols appears to react by $${S_N}1$$ mechanism.
