The chemical formula of Lucas reagent is
Show Hint
- Anhy. \( \text{ZnCl}_2 / \text{HCl} \)
- \( \text{C}_6\text{H}_5\text{SO}_2\text{Cl} \)
- NaOH + CaO
- HNO\(_2\)
The Correct Option is A
Solution and Explanation
Lucas reagent is a mixture of concentrated hydrochloric acid and anhydrous zinc chloride. It is used to test for primary, secondary, and tertiary alcohols by classifying them based on the rate of formation of turbidity (alkyl halide).
Top Questions on Alcohols
Alcohols undergo a number of reactions involving the cleavage of C – OH bond. However, phenols do not undergo reactions involving the cleavage of C – OH bond. Alcohols are weaker acids than water. Alcohols react with halogen acids to form the corresponding haloaklanes. Phenols are stronger acids than alcohols. A charac- teristic feature of phenols is that they undergo electrophilic substitution reactions such as halogenation, nitration, etc. Since –OH group is a strong activating group, phenol gives trisubstituted products during halogenation, nitration, etc.
- Which of the following is a primary alcohol?
- Which of the following contains 2 primary –OH groups in its structure?
- Ethanol is made unfit for drinking by adding?
- Which reagent will best convert alcohol to aldehyde selectively?
