Alcohol + Lucas reagent overset arrow Immediate turbidity How many of the following will give above test positive? 2- Methylpropan -2- ol, butan -1- ol, 2- methylpropan -1- ol, 2,2- dimethylpropan -1- ol, 2,4- dimethylpentan -2- ol, propan- 1,3- diol (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

Tertiary alcohols like 2 -methylpropan- 2 -ol, 2,4 -dimethylpentan- 2 -ol react immediately with Lucas reagent (. conc. HCl + anhydrous .ZnCl 2) at room temperature.

Q. Alcohol $+$ Lucas reagent $\to$ Immediate turbidity
How many of the following will give above test positive?
$2 -$ Methylpropan $- 2 -$ ol, butan $- 1 -$ ol, $2 -$ methylpropan $- 1 -$ ol, $2, 2 -$ dimethylpropan $- 1 -$ ol, $2, 4 -$ dimethylpentan $- 2 -$ ol, propan- $1, 3 -$ diol

Tertiary alcohols like $2$ -methylpropan- $2$ -ol, $2, 4$ -dimethylpentan- $2$ -ol react immediately with Lucas reagent $($ conc. $H Cl +$ anhydrous $Z n C l_{2})$ at room temperature.
