हिन्दीGiven below are two statements: Statement I: In Lucas test, primary, secondary and tertiary alcohols are distinguished on the basis of their reactivity with conc. \( \text{HCl} + \text{ZnCl}_2 \) known as Lucas reagent. Statement II: Primary alcohols are most reactive and immediately produce turbidity at room temperature on reaction with Lucas reagent. In the light of the above statements, choose the most appropriate answer from the options given below:
Correct answer · Option 1
Statement I is correct but Statement II is incorrect.
Explanation
Tertiary alcohols react fastest with Lucas reagent producing immediate turbidity, whereas primary alcohols do not react at room temperature. Thus, Statement I is correct and Statement II is incorrect.
