Question

name the product that is formed by dehydration of ethanol in conc sulphuric acid​

Answer 1

Answer:

Ethanol is heated with an excess of concentrated sulphuric acid at a temperature of 170°C. The gases produced are passed through sodium hydroxide solution to remove the carbon dioxide and sulphur dioxide produced from side reactions.

Answer 2

Answer:

Ethene is formed.

Explanation:

when ethanol is heated in presence of con sulfuric acid,

On heating it results in formation of ethene and water.

we know that sulfuric acid is a very good dehydrating agent and dhire to its properties, it dehydrates ethanol this resulting in breaking of ethanol and due to which one molecule of water is separated from ethanol.

This is the following equation

C2H5OH -conc H2SO4---> C2H4 + H2O
