Here's a breakdown:
* -ane: Indicates a single bond between carbon atoms (e.g., methane, ethane).
* -ene: Indicates a double bond between carbon atoms (e.g., ethene, propene).
* -yne: Indicates a triple bond between carbon atoms (e.g., ethyne, propyne).
Example:
* Ethyne (C2H2): This molecule has a triple bond between the two carbon atoms.
* Propyne (C3H4): This molecule has a triple bond between the first and second carbon atoms.
The presence of a triple bond significantly affects the molecule's geometry and reactivity. Triple bonds are shorter and stronger than single or double bonds, and they introduce a linear geometry around the triple-bonded carbons.
