Question
When ethanol is heated with concentrated sulphuric acid at 170°C, it gets converted into ethene. In this reaction, concentrated sulphuric acid acts as:
(a) oxidising agent
(b) catalyst
(c) dehydrating agent
(d) reducing agent

Solution
dehydrating agent
Sulphuric acid acts as a dehydrating agent as it removes water molecules from the alcohol (ethanol), and converts it to ethene.
