Directions: Each question contains Statement- 1 and Statement-2 and has the following choices (a), (b), (c) and (d), out of which ONLY ONE is correct. (a) Statement- 1 is True, Statement- 2 is True; Statement- 2 is a correct explanation for Statement- 1 (b) Statement- 1 is True, Statement- 2 is True; Statement- 2 is NOT a correct explanation for Statement- 1 (c) Statement- 1 is True, Statement- 2 is False (d) Statement- 1 is False, Statement- 2 is True Statement 1 Tertiary alcohols produce immediate turbidity with Lucas reagent. and Statement 2 The order of reactivity of alcohols is $3^{\circ}>2^{\circ}>1^{\circ}$ in all chemical reactions.
In Lucas test, the correct statement is / are (A) Alcohols are soluble in Lucas reagent (B) Halides obtained as a product are immiscible in Lucas reagent and produce turbidity in solution (C) Lucas reagent is concentrated $\mathrm{HCl}$ and $\mathrm{ZnCl}_{2}$ (D) Primary alcohols produce turbidity at room temperature

Luca's test of alcohols involves following reaction: $\mathrm{R}-\mathrm{OH}+\mathrm{HCl} \frac{\text { anhydrous }}{\mathrm{ZnCl}_{2}} \underset{\text { white turbidity }}{\mathrm{RCl}+\mathrm{H}_{2} \mathrm{O}}$ Select the correct statement(s) for the Luca's test. (a) Lesser the acidic character of alcohol, greater is its reactivity towards Luca's reagent. (b) ROH behaves as a base. (c) $\mathrm{CH}_{3} \mathrm{OH}$ gives Luca's test most quickly. (d) Reactivity of $1^{\circ}, 2^{\circ}, 3^{\circ}$ alcohol, lies in the following sequence (for Luca's reaction $3^{\circ}>2^{\circ}>1^{\circ}$ ).
