Alcohols (i) CH(3)CH(2)CH(2)OH, (ii) CH(...

Alcohols (i) `CH_(3)CH_(2)CH_(2)OH, (ii) CH_(3)-CHOH-CH_(3)` and `(iii) CH_(3)-C(CH_(3))(OH)-CH_(3)` were treated 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
