What happens when ethanol and ethanoic acid react in the presence of acid catalyst?
When ethanol and ethanoic acid react in the presence of an acid catalyst, they undergo an esterification reaction to form ethyl ethanoate (ester) and water. This reaction is reversible and reaches equilibrium. The acid catalyst helps to increase the rate of the reaction but does not affect the overall stoichiometry.

What happens when ethanol is heated in presence of concentrated H2SO4?
When ethanol is heated in the presence of concentrated H2SO4, it undergoes dehydration to form ethylene gas. This reaction follows an elimination mechanism where a water molecule is eliminated from ethanol to produce ethylene.
What happens when bromine is mixed with benzene with an FeBr3 catalyst?
When bromine is mixed with benzene in the presence of FeBr3 catalyst, bromination of benzene occurs. The FeBr3 catalyst activates the bromine molecule to form a bromine cation, which then electrophilically attacks the benzene ring, replacing a hydrogen atom with a bromine atom. This results in the formation of bromobenzene.
What happens to ethanol at C?
At 78.37°C, ethanol boils and undergoes a phase change from liquid to gas. It turns into ethanol vapor, which can be collected and condensed back into liquid ethanol through condensation.
What happens when ethanol is treated with PCl5?
When ethanol is treated with PCl5, it undergoes a substitution reaction where the hydroxyl group (-OH) of ethanol is replaced by a chlorine atom. This results in the formation of ethyl chloride and phosphorous oxychloride as byproduct.
What happens when NaHCo3 reacts with ethanoic acid?
When sodium bicarbonate (NaHCO3) reacts with ethanoic acid (CH3COOH), it forms sodium acetate (CH3COONa), water (H2O), and carbon dioxide gas (CO2). This is a neutralization reaction where the acid and base react to form a salt, water, and carbon dioxide.
What happens when ethanol is heated in presence of concentrated H2SO4?
When ethanol is heated in the presence of concentrated H2SO4, it undergoes dehydration to form ethylene gas. This reaction follows an elimination mechanism where a water molecule is eliminated from ethanol to produce ethylene.
What happens when ethanol is oxidised with acidified kmno4 solution?
When ethanol is oxidized with acidified KMnO4 solution, it undergoes complete oxidation to form ethanoic acid (acetic acid). The purple KMnO4 solution is reduced to green Mn2+ ions in the process.
What happens when ethanol is treated with HI in presence of red phosphorus?
The ethyl iodide is formed.
What are three factors of the speed at which a chemical reaction happens?
temperature presence or absence of a catalyst concentration of reactants
What happens when a bottle is filled with ethanol?
nothing happens
What happens to catalyst in a reaction?
it is incorporated into the reactants
What happens when bromine is mixed with benzene with an FeBr3 catalyst?
When bromine is mixed with benzene in the presence of FeBr3 catalyst, bromination of benzene occurs. The FeBr3 catalyst activates the bromine molecule to form a bromine cation, which then electrophilically attacks the benzene ring, replacing a hydrogen atom with a bromine atom. This results in the formation of bromobenzene.
What happens to the freezing points as the ethanol concentration increased?
The answer depends on the substances in the mixture in which the ethanol concentration increases.
What happens to a chemical reaction without a catalyst?
he is a pagal
What happens to ethanol at C?
At 78.37°C, ethanol boils and undergoes a phase change from liquid to gas. It turns into ethanol vapor, which can be collected and condensed back into liquid ethanol through condensation.
What happens when ethanol is mixed with vinegar?
Probably nothing since vinegar is a dilute concentration of acetic acid...However if you had pure acetic acid & ethanol the two would react to form an ester called ethyl acetate at room temperature: CH3CH2OH (ethanol) + CH3COOH (acetic acid) <==> CH3COOCH2CH3 (ethyl acetate) + H2O However since it is an equilibrium reaction you'd have a mixture of the products & reactants & would need to separate the mixture. Under the presence of an acid catalyst (such as sulfuric acid) & continuously removing the water you can increase the yield of ethyl acetate.
What happens when potassium iodide react with 2 moles sulphur in presence of moonlight?
When potassium iodide reacts with sulphur in the presence of moonlight, the reaction results in the formation of potassium sulphide and iodine. Moonlight can act as a catalyst for this reaction, helping to facilitate the conversion of the reactants into the products.
