The hydroxyl compound that gives a precipitate immediately when treated with concentrated HCl and anhydrous `ZnCl_(2)` is `:`

A

3-methyl-2-butanol

B

3-methyl-1-butanol

C

1-butanol

D

2-methyl-2-butanol

Text Solution

Verified by Experts

The correct Answer is:
D

Mechanism of this reaction involves the formation of carbocation and the 3° carbocation is most stable. In the above reaction 3° carbocation is formed. Hence, when hydroxyl compound is treated with cone. HCI, the precipitate of 2-chloro-2-methylbutane is formed immediately.
