Question

Which one of the following alcohols reacts instantaneously with Lucas reagent?

• A. \(\text{CH}_{3}-\text{CH}(\text{CH}_{3})-\text{CH}_{2}\text{OH}\)
• B. \(\text{CH}_{3}-\text{C}(\text{CH}_{3})(\text{OH})-\text{CH}_{3}\)
• C. \(\text{CH}_{3}-\text{CH}_{2}-\text{CH}_{2}-\text{CH}_{2}\text{OH}\)
• D. \(\text{CH}_{3}-\text{CH}_{2}-\text{CH}(\text{OH})-\text{CH}_{3}\)
• E.

Hint:

Identify the degree of the alcohol by counting the carbons attached to the C-OH carbon.
Instant turbidity = \(3^{\circ}\) Alcohol.
Delayed turbidity = \(2^{\circ}\) Alcohol.
No reaction = \(1^{\circ}\) Alcohol.
