Question

Dehydration of ethanol by concentrated sulfuric acid forms

Select one:
a. Ethane
b. Ethene
c. Ethyne​

Answer 1

Ethanol can be dehydrated to give ethene by heating it with an excess of concentrated sulphuric acid at about 170°C. Concentrated phosphoric(V) acid, H3PO4, can be used instead. The acids aren't written into the equation because they serve as catalysts.
