Eight mL of concentrated sulfuric acid has been cautiously added to 4 mL of water in 50 mL ground-glass stopper conical flask. The solution has been cooled in an ice bath until cold to the hand. Ten mL of cyclohexene has been added into the solution. The flask has been sealed with a greased ground glass stopper and it has been vigorously shaken for at 15 minutes until there was one homogeneous layer. The reaction mixture has been left for 10 minutes to increase completeness of reaction. The mixture has been poured into a 250-mL round-bottom flask, the previous conical flask has been rinsed with 125ml of water, and the rinsing has been added into the round-bottom flask. The flask has been fitted with a distillation adapter and a condenser set for distillation. The mixture has been heated to hydrolyze the intermediate and to distill the product. The distillate has been collected into a 100 mL conical flask. The distillation has been stopped once the distillate in the condenser was clear, with no oily droplets present and phase is left in the pot. The distillate has been saturate with 10 grams of sodium chloride. The mixture has been left for 15 minutes. The mixture has been transferred into a 250 mL reparatory funnel. The conical flask has been rinsed with 3 mL of diethyl ether for 3 times. All rinsing has been added to the reparatory funnel. The reparatory funnel has been shaken until two distinct layers were seen. The top layer has been transferred into a 100 mL conical flask. The ethereal extract has been dried by added anhydrous potassium carbonate until free flowing. The mixture has been gravity filtrated through fluted filter paper in to a 50 mL round bottom flask. The filtrate has been distilled and the distillate has been collect form as cyclohexanol. The distillation has been stopped when the temperature dropped. The sample and the bottle have been weighted to obtain the number of grams of cyclohexanol produced. The theoretical yield of cyclohexanol and the percent yield have been calculated.
What else can I help you with?
Why cyclohexanol does not dissolve in aqueous sodium hydroxide?
Cyclohexanol hasn't a polar molecule.
What is the color for the mixture of cyclohexanol with water?
Neither water nor cyclohexanol have color and the (partially) inhomogenous mixture might look milky turbid
What equation shows the synthesis of cyclohexanone from cyclohexanol and what is this synthesis?
The synthesis of cyclohexanone from cyclohexanol involves oxidation of the alcohol functional group to a ketone. This transformation can be achieved by using an oxidizing agent, such as Jones reagent (CrO3 in H2SO4) under acidic conditions. The chemical equation for this oxidation is as follows: Cyclohexanol + Jones reagent → Cyclohexanone + Cr byproducts.
How can ir spectroscopy be used to show cyclohaxanone has been converted into cyclohexanol?
In the IR spectrum of cyclohexanone, a carbonyl peak around 1700 cm^-1 (C=O stretch) would be present. After conversion to cyclohexanol, this peak would disappear as the carbonyl functional group is reduced to a hydroxyl group. A new peak would appear around 3200-3600 cm^-1, corresponding to the O-H stretch of the alcohol group in cyclohexanol.
What does cyclohexanol dissolve best in?
Cyclohexanol is most soluble in polar solvents such as water, due to its ability to form hydrogen bonds. It can also dissolve in organic solvents like ethanol or acetone.
What is the product of chlorocyclohexane and sodium hydroxide?
The reaction between chlorocyclohexane and sodium hydroxide typically results in an elimination reaction known as an E2 reaction. This reaction will form cyclohexene as the main product with sodium chloride as a byproduct.
Why cyclohexanol does not dissolve in aqueous sodium hydroxide?
Cyclohexanol hasn't a polar molecule.
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.
Why is glucose more soluble in water than cyclohexanol?
Glucose is more soluble in water than cyclohexanol because glucose is polar. In contrast, cyclohexanol is mostly nonpolar and therefore less soluble in water.
What is the role of LDA in the deprotonation of cyclohexanol?
In the deprotonation of cyclohexanol, LDA (lithium diisopropylamide) acts as a strong base to remove a proton from the hydroxyl group of cyclohexanol, forming cyclohexoxide. This reaction is important in organic synthesis to create new compounds.
Does Cyclohexene has a lower boiling point than either cyclohexanol?
Yes, cyclohexene has a lower boiling point than cyclohexanol. This is because cyclohexene is a hydrocarbon with weaker intermolecular forces (London dispersion forces) compared to cyclohexanol, which has additional hydrogen bonding interactions.
What is the density of Cyclohexanol?
The density of Cyclohexanol at room temperature is approximately 0.964 g/cm³.
What is the color for the mixture of cyclohexanol with water?
Neither water nor cyclohexanol have color and the (partially) inhomogenous mixture might look milky turbid
What is the chemical reaction when cyclohexanol react with acid sulphuric?
The reaction between cyclohexanol and sulfuric acid typically results in dehydration, forming cyclohexene. The sulfuric acid acts as a catalyst to remove a water molecule from the cyclohexanol molecule, leading to the formation of the alkene product.
What effects cyclohexanol on the environment?
Cyclohexanol is considered to be a high volume chemical. It can be harmful to the environment because it is extremely toxic. If animals accidentally consume it, they will likely die.
What equation shows the synthesis of cyclohexanone from cyclohexanol and what is this synthesis?
The synthesis of cyclohexanone from cyclohexanol involves oxidation of the alcohol functional group to a ketone. This transformation can be achieved by using an oxidizing agent, such as Jones reagent (CrO3 in H2SO4) under acidic conditions. The chemical equation for this oxidation is as follows: Cyclohexanol + Jones reagent → Cyclohexanone + Cr byproducts.
Are cyclohexanol soluble in aqueous sodium hydroxide?
Yes, cyclohexanol is soluble in aqueous sodium hydroxide because it can undergo deprotonation to form the water-soluble cyclohexoxide ion.
