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 reaction with 3-methyl-1-hexanol?
methylhexanoic
Why is the Lucas test applicable only to alcohols containing not more than five carbons?
First, my text says that the Lucas test is not applicable to compounds with six carbons or more. This is due to the solubility of the compound in the reagent. A compound with more than six carbons is to large to be dissolved in the reagent and therefore will not react in most cases.
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 reaction for 2-butanol with the lucas reagent?
Since 2-butanol is a secondary alcohol, it will form a cloudy precipitate after approximately 5-6 minutes.
What is the function of nessler's reagent?
nessler's reagent
Chemical formula for the reaction of ethanol and lucas reagent?
balanced equation for ethanol and lucas reagent
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 the reaction of propanol to lucas reagent?
2-Methyl-1-propanol is a primary alcohol and so will not react with Lucas reagent at room temperature.Cyclopentanol is a secondary alcohol and so will react with Lucas reagent in 3-5 minutes (solution turns cloudy). Cyclopentyl chloride is the result.1-Methylcyclopentanol is a tertiary alcohol and so will react immediately with Lucas reagent to produce turbidity. 1-Chloro-1-methylcyclopentanol is the result.
Lucas' reagent reaction with 3-methyl-1-hexanol?
methylhexanoic
Is Lucas test applicable for cyclohexanol?
The Lucas test is applicable for cyclohexanol. Cyclohexanol is a secondary alcohol and s reported to react with the Lucas reagent after a few minutes.
Why is the zinc chloride in Lucas reagent anhydrous?

Why lucas test is limited to monofunctional which contain less than six carbon atoms?
The Lucas Test is limited to alcohols which are soluble in the Lucas reagent, because otherwise, the test will not produce the second insoluble layer. These also include some poly-functional alcohols, and often have less than 6 carbon atoms.
What is tollen's reagent and baeyer's reagent?
tollen's reagent = [Ag(NO)2]+ baeyer's reagent= KMnO4
Equation of formaldehyde schiff's reagent benzaldehyde schiff's reagent and acetone schiff's reagent?
