How is ethene prepared from ethyl alcohol

Answers

Answered by zaratariq27

Answer:

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.
