rate with Lucas reagent 3°> 2°> 1°

Q. Alcohols (i) $C H_{3} C H_{2} C H_{2} O H$ (ii) $C H_{3} - C H O H - C H_{3}$ and (iii) $C H_{3} - C (C H_{3}) (O H) - C H_{3}$ were treated with Lucas reagent (Conc. $H Cl + Z n C l_{2})$ What results do you expect at room temperature?

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

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

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

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

rate with Lucas reagent $3^{\circ} > 2^{\circ} > 1^{\circ}$
