Which of the following reagents can distinguish between `t-`butyl alcohol and `n-`butyl alcohol?

Options

A. sodium
B. `ZnCl_(2) and Conc. HCl`
C. `AgNO_(3) and NH_(4)^(+)OH^(-)`
D. `CuCl_(2) and NH_(4)^(+)OH^(-)`

Answer

B

Explanation

The difference in reactivity of three classes of alcohols with `HCl` distinguishes them from one another (Lucas test). Alcohols are soluble in Lucas reagent (conc. HCl and anhydrous `ZnCl_(2))` while their halides are immicible and produce turbidity is produced immediately as they form the halides easily. primary alcohols (such as `n-`butyl alcohol), do not produce turbidity at room temperature.
