Student A conducted the acid-catalyzed dehydration of ethanol at 180°C and obtained a gaseous product. Student B conducted the same experiment at 140 °C and obtained a lowboiling liquid. What were the products that each of the students made? Draw mechanisms for the formation of these products. What could account for the formation of two different products?(Hint: Consider what other reactions might compete with an elimination under
these conditions.)

ethylene is the gas.
diethyl ether is the other.
Here is a site where you can read about them.

The boards don't support drawing mechanisms or diagrams. I think I may be able to find a mechanism on the web. If so I'll post a link.
