Question

Which of the following alcohols reacts most readily with Lucas reagent?

• A. $CH_{3}CH_{2}CH_{2}OH$
• B.
• C. $\begin{matrix} CH_{3} \\ | \\ CH_{3} - C - OH \\ | \\ CH_{3} \end{matrix}$
• D.

Answer 1

Answer: (C)

$\begin{matrix} CH_{3} \\ | \\ CH_{3} - C - OH \\ | \\ CH_{3} \end{matrix}$

Answer 2

The rate of reaction with Lucas reagent is $3º > 2º > 1º$

Tertiary alcohos immediately react to give turbidity secondary alcohols after some time and primary alcohols do not give turbidity until heated.
