What is the correct order of reactivity of alcohols in the following reaction?
| 1. | 1° > 2°> 3° | 2. | 1° < 2°> 3° |
| 3. | 3°> 2°> 1° | 4. | 3°> 1°> 2° |
Hint: Lucas Reagent
The given reaction is nucleophilic substitution reaction in which -OH group is replaced by -Cl. Tertiary alcohols, when react with HCI in presence of form tertiary carbocation.
This intermediate 3° carbocation is more stable than 2° carbocation as well as 1° carbocation. Higher the stability of intermediate, higher will be the reactivity of reactant molecule
So, the order of reactivity of alcohols in the given reaction is 3° > 2°> 1° and correct
