Three alcohols
(i) `CH_3CH_2CH_2OH,`
(ii) `CH_3-CHOH-CH_3and`
(iii) `CH_3-C(CH_3)(OH)-CH_3`
were treated seperately with Lucas reagent (Conc. `HCl+ZnCl_2`) . What results do you expect at room temperature.

A

(ii) and (iii) react immediately and (i) in about 5 minutes

B

(iii) reacts immediately, (ii) reacts in about 5 minutes and (i) not at all

C

(i) reacts immediately, (ii) reacts in about 5 minutes and (iii) not at all

D

(i) reacts in about 5 minutes, (ii) reacts in about 15 minutes and (iii) not at all

Text Solution

Verified by Experts

The correct Answer is:
B
Tertiary alcohol reacts immediately, secondary alcohol reacts in about 5 minutes and primary alcohol does not react at room temperature with Lucas reagent.
