Why doesn't acetyl chloride exhibit a haloform reaction even though it has a keto-methyl group?
The chemistry of acetyl chloride is not as a methyl ketone but as an acyl halide. All the action is on the carbon atom with the oxygen and chlorine. In the haloform reax the methyl carbon gets attacked losing a proton, picking up a halide and leaving an OH behind to form an acid and a haloform.
Chemical formula for the reaction of ethanol and lucas reagent?
The chemical formula for the reaction of ethanol with Lucas reagent (concentrated HCl and ZnCl2) is C2H5OH + HCl → C2H5Cl + H2O. This reaction converts ethanol into ethyl chloride by substitution of the hydroxyl group with a chlorine atom.
What is the heat of reaction for ethanol fermentation from glucose?
The heat of reaction for ethanol fermentation from glucose is exothermic, meaning it releases heat. This is because the process of fermentation involves breaking down glucose to produce ethanol and carbon dioxide, which releases energy in the form of heat.
C2H4 plus H2O equals?
The chemical equation for the reaction of C2H4 with H2O is C2H4 + H2O → C2H5OH (ethanol). This reaction results in the formation of ethanol by adding water across the carbon-carbon double bond in ethylene (C2H4).
What is the role of ethanol in saponification?
Ethanol is sometimes used in saponification processes as a solvent to dissolve oils and fats, which helps facilitate the reaction between the fats and the alkali to produce soap. Ethanol can also act as a catalyst to speed up the saponification reaction.

Why is hydrochloric acid used in a haloform reaction?
Hydrochloric acid is used in a haloform reaction to provide the chloride ions needed for the reaction to take place. The chloride ions participate in the halogenation step of the reaction, leading to the formation of the haloform product.
What is the SN1 reaction that produces ethanol from chloroethane?
In an SN1 reaction, chloroethane undergoes nucleophilic substitution to form ethanol. The chloroethane molecule first undergoes heterolytic cleavage to form a carbocation intermediate. Then, a nucleophile such as water attacks the carbocation, resulting in the formation of ethanol as the final product.
Will acetaldehyde give positive haloform reaction?
Yes. The alpha protons on the methyl group will be deprotonated and react with halides and eventually form a trihaloform group or (-C-CX3). The Trihalofrom is explelled when a OH group attacks the carbonyl carbon. This forms the trihaloform carbanion of the carboxylic acid. The anion takes a hydrogen from the acid to form the haloform and a carboxylic salt
In iodoform test can you use ethanol instead of water?
No, you should not use ethanol instead of water when conducting the iodoform test. The test relies on the reaction of iodine with an alcohol in the presence of a base, typically sodium hydroxide, to form iodoform. Water is usually used in the test to help facilitate the reaction. Substituting ethanol for water can affect the outcome of the test.
Equation for the reaction of ethanol with fehling reagent?
The reaction of ethanol with Fehling's reagent involves oxidation of ethanol to acetaldehyde. The equation is: CH3CH2OH + 2Cu2+ + 4OH- → CH3CHO + 2Cu2O + 3H2O
What is the reaction from sugar to ethanol called?
The reaction from sugar to ethanol is called fermentation. This process involves the conversion of sugars such as glucose into ethanol and carbon dioxide by yeast or bacteria in the absence of oxygen.
How does ethanol evaporation affect the efficiency of a chemical reaction?
Ethanol evaporation can affect the efficiency of a chemical reaction by changing the concentration of reactants and products in the reaction mixture. When ethanol evaporates, the volume of the reaction mixture decreases, leading to a higher concentration of the remaining components. This can potentially alter the reaction rate and equilibrium, impacting the overall efficiency of the reaction.
Chemical formula for the reaction of ethanol and lucas reagent?
The chemical formula for the reaction of ethanol with Lucas reagent (concentrated HCl and ZnCl2) is C2H5OH + HCl → C2H5Cl + H2O. This reaction converts ethanol into ethyl chloride by substitution of the hydroxyl group with a chlorine atom.
Why is the conversion of ethanol to ethnoic acid an oxidation reaction?
The conversion of ethanol to ethanoic acid involves adding oxygen to ethanol, which increases the oxidation state of carbon from -2 in ethanol to +2 in ethanoic acid. This increase in oxidation state indicates that oxidation has occurred, making it an oxidation reaction.
Prepare chloroform from ethyl alcohol by haloform reaction?
To prepare chloroform from ethyl alcohol using the haloform reaction, you would first convert the ethyl alcohol to acetaldehyde by oxidizing it with an oxidizing agent like sodium hypochlorite. Then, treat the acetaldehyde with a strong base like sodium hydroxide to produce chloroform through a series of reactions involving halogenation and halide exchange. Finally, separate and purify the chloroform from the reaction mixture.
What is the equation of the reaction between ethanol and ethanoic acid?
The reaction between ethanol and ethanoic acid produces ethyl acetate and water in the presence of a catalyst like concentrated sulfuric acid. The equation for this reaction is: Ethanol + Ethanoic acid → Ethyl acetate + Water
