What happens when ethanol is heated with concentrated sulphuric acid?
When ethanol is heated with an excess of concentrated sulphuric acid at a temperature of 170°C, it produces ethene as final product. The concentrated acid acts only as a dehydrating agent and it is recovered unchanged. Was this answer helpful? 0
What happens when ether reacts with ethanol at 180 degrees Celsius?
Meantime, the ether can continue to react with ethanol to form more alkene. At 180 C, water (a product) is removed to drive everything ultimately to alkene. Once the water volatilized, the alkene reaction is irreversible. I totally came up with this in my head, so I could be wrong.
What happens when ethanol is heated at 443 K?
(I) When ethanol is heated, excess of H 2 S O4 at 443 K dehydrogenation reaction takes place. Dehydrogenetion is basically the removal of water molecule.
Why does ethanol act as a nucleophile in H2SO4?
H2SO4 protonates water to make the -OH a good leaving group, and ethanol acts as a nucleophile to displace the H2O in an irreversible process. Eliminations of primary functionalities are not going to happen at the lower temperature because the ethanol is protonated and thus an EXTREMELY poor base.

When ethanol is heated with concentrated sulphuric acid at 170oC, it gets dehydrated to form ethene (unsaturated hydrocarbon). This reaction is termed as dehydration reaction as it involves the removal of water molecules from the alcohol (ethanol).
What happens when ethanol is heated in the presence of conc sulphuric acid at a temperature of 443K?
When ehanol is heated with concentrated sulphuric acid at 443 K, dehydration takes place and ethene is formed. In this reaction concentrated sulphuric acid acts as a dehydrating agent.
What happens when ethanol is heated with excess concentrated sulphuric acid write the necessary chemical equation?
When ethanol is heated with excess amount of concentrated sulphuric acid then it will give out ethene and water. The concentratic H2SO4 is known as dehydrating agent and it gives unsaturated hydrocarbon.
What happens when ethanol is heated with concentrated sulphuric acid at 453k explain the mechanism of this reaction?
When ethanol is heated with conc. sulphuric acid at 453k, dehydration takes place and ethene is formed. In this reaction sulphuric acid acts as a dehydrating agent.
What is the product obtained by the reaction of ethanol with conc H2SO4 at 413k explain with mechanism?
(1) At 383 K, ethanol reacts with sulphuric acid to form ethyl hydrogen sulphate and water. (2) At 413 K, ethanol reacts with sulphuric acid to form diethyl ether.
What is the major product when ethanol is treated with conc H2SO4 at 413 K?
(2) At 413 K, ethanol reacts with sulphuric acid to form diethyl ether. As, the two molecules of ethanol combine to remove water.
What is the product obtained by heating an excess of ethanol?
Ethyl alcohol, on heating at 165∘−170∘C with conc. H2SO4 gives ethylene.
