The chemical formula of Lucas reagent is
- A Anhy. \(\mathrm{ZnCl}_2 / \mathrm{HCl}\)
- B \(\mathrm{C}_6 \mathrm{H}_5 \mathrm{SO}_2 \mathrm{Cl}\)
- C \(\mathrm{NaOH}+\mathrm{CaO}\)
- D \(\mathrm{HNO}_2\)
Answer & Solution
Correct Answer
(A) Anhy. \(\mathrm{ZnCl}_2 / \mathrm{HCl}\)
Step-by-step Solution
Detailed explanation
Lucas reagent is a solution of anhydrous zinc chloride (\(\mathrm{ZnCl}_2\)) in concentrated hydrochloric acid (\(\mathrm{HCl}\)). It is used to classify alcohols based on their reactivity towards the substitution reaction, where primary, secondary, and tertiary alcohols react…
