Answer 2

Dear Student,

◆ Answer -

The product that is formed by dehydration of ethanol in conc. sulphuric acid is ethene.

● Explaination -

Ethanol (CH3-CH2-OH) when treated with conc.H2SO4, dehydrates to give ethene (CH2=CH2). Conc.H2SO4 acts as a catalyst in this reaction. Water is formed as a byproduct.

CH3-CH2-OH --> CH2=CH2 + H2O

Thanks dear. Hope this helps you...
