Answer 1

Ethene and ethyne are the correct IUPAC chemical names for ethylene and acetylene, respectively.

Explanation:

The middle letter indicates the number of bonds between the carbon atoms.
Ethane = single bond
Ethene = double bond
Ethyne = triple bond

The common "trade names" of many chemicals evolved over years of discovery and use, and due to familiarity and "installed base" many of them are still in use.
