Question

Which of the following alcohols reacts fastest with Lucas reagent?
[0.77 Mark]

• A. $C{H}_{3}C{H}_{2}OH$
• B. $C{H}_3-\stackrel{C{H}_3}{\stackrel{|}{\underset{C{H}_3}{\underset{|}{C}}}}-OH$
• C. $C{H}_3-\stackrel{C{H}_3}{\stackrel{|}{C}H}-C{H}_2-OH$
• D. $C{H}_{3}OH$

Answer 1

The correct option is B $C{H}_3-\stackrel{C{H}_3}{\stackrel{|}{\underset{C{H}_3}{\underset{|}{C}}}}-OH$

More is the stability of the carbocation so formed, more will be the reactivity of the alcohol towards Lucas reagent.
Therefore tertiary alcohol reacts faster with Lucas reagent.
