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 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?
Tertiary react immediately, secondary takes about 5-10 minutes and primary alcohols do not react under standard conditions
What type of covalent bond is ZnCl2?
Zinc chloride is an ionic compound due to the bond between the metal and non-metal.
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

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.
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.
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.

Hydrogen Chloride gas --> HCl or Hydrochloric Acid --> HCl(aq)

Tertiary react immediately, secondary takes about 5-10 minutes and primary alcohols do not react under standard conditions
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 type of covalent bond is ZnCl2?
Zinc chloride is an ionic compound due to the bond between the metal and non-metal.
