Lucas reagent is used to test what homologous series?
Lucas reagent is used to test for the presence of alcohols in a substance. It is made from anhydrous zinc chloride and concentrated hydrochloric acid.
Is Lucas test applicable for cyclohexanol?
Yes, the Lucas test can be applicable for cyclohexanol. The test involves the reaction of an alcohol with hydrochloric acid and zinc chloride to form an alkyl chloride. In the case of cyclohexanol, this reaction will convert it into cyclohexyl chloride.
What is the reaction of propanol to lucas reagent?
Propanol will react with Lucas reagent (concentrated hydrochloric acid and zinc chloride) to form protonated alcohol and alkyl chloride. The reaction rate will depend on the type of propanol (1-propanol or 2-propanol) due to the different reactivity of the hydroxyl groups.
What reagent is reacted with zinc carbonate to form zinc chloride?
Hydrogen Chloride gas --> HCl or Hydrochloric Acid --> HCl(aq)
What happens to a tertiary alcohol with lucas reagent?
A tertiary alcohol does not react with Lucas reagent (ZnCl2 and HCl) and does not form a white precipitate, meaning it does not undergo a substitution reaction. Lucas reagent is primarily used to test for the presence of primary or secondary alcohols, as they react to form alkyl chlorides which are insoluble and precipitate out.
What is Lucas reagent?
This is a mixture of concentrated hydrochloric acid and anhydrous zinc chloride (which acts as a catalyst). To prepare, mix 136.29 g of anhydrous zinc chloride (ZnCl2) with 105 g of concentrated hydrochloric acid (HCl). Place beaker in an ice bath, due to the exothermic reaction. Stir with a glass rod until all ZnCl2 is dissolved.
Lucas reagent is used to test what homologous series?
Lucas reagent is used to test for the presence of alcohols in a substance. It is made from anhydrous zinc chloride and concentrated hydrochloric acid.
What is Lukas's reagent?
Lucas' reagent is a solution of anhydrous zinc chloride in concentrated hydrochloric acid used to classify low molecular weights of alchohols. In 1930, this test became the standard method in qualitative organic chemistry.
What is the result when a Lucas test is done on a Phenol?
A positive Lucas test on phenol would indicate that phenol is a strong enough acid to react with Lucas reagent (a mixture of concentrated hydrochloric acid and zinc chloride) to form a cloudy solution or a precipitate. This reaction distinguishes phenol from other alcohols that do not react with the Lucas reagent.
Is Lucas test applicable for cyclohexanol?
Yes, the Lucas test can be applicable for cyclohexanol. The test involves the reaction of an alcohol with hydrochloric acid and zinc chloride to form an alkyl chloride. In the case of cyclohexanol, this reaction will convert it into cyclohexyl chloride.

What reagents would you use for the synthesis of 1-chlorobutane from 1-butanol?
anhydrous Zinc chloride and aq.HCl or CaCl2 and HCl.
What is the function of anhydrous zinc chloride in the formation of fluorescein?
Zinc Chloride catalyses the reaction of e.g. phatalic anhydride and resorcinol. If you head these three as powdered substances with a bunsenburner, they react much faster. After solving this mixture in water, you can filtrate the Zinc Cholride out of the solution. For more examples what a catalyst does, read Wiki or Google catalyst. Good Luck
Why are 2 layers of liquid formed in lucas test?
The Lucas test is used to determine the number of alkyl groups present in a compound. It is based on the fact that the compound to be tested is mixed with Lucas reagent, which is a solution of anhydrous zinc chloride in concentrated hydrochloric acid. If the compound has one alkyl group, then a single layer of liquid is formed. If the compound has two alkyl groups, then two layers of liquid are formed.
What is the formula of zink chloride?
The formula for zinc chloride is ZnCl2. This compound is made up of one zinc ion and two chloride ions.
