Question
Conversion of ethanol to ethene by the action of concentrated sulphuricacid is an example of ____________. (dehydration / dehydrogenation /dehydrohalogenation)
Solution
The conversion of ethanol to ethene by the action of concentrated sulphuric acid is an example of dehydration.
Here's the step by step process:
-
Ethanol (C2H5OH) reacts with concentrated sulphuric acid (H2SO4), which acts as a dehydrating agent.
-
The sulphuric acid removes a molecule of water (H2O) from the ethanol. This is why it's called a dehydration reaction.
-
The removal of water results in the formation of ethene (C2H4), along with the water molecule.
So, the correct answer is dehydration.
