Question
Methane does not undergo addition reaction, but ethane does.
✓

Answer

Alkanes are saturated, i.e. they do not have a carbon-to-carbon double bond, and so do not undergo an addition reaction. Alkenes are said to be unsaturated because of the carbon-to-carbon double bond in their structure, and the double bond in alkenes makes them more reactive than alkanes.
