Two carbon compounds have the prefix eth-, the prefix pro - applies to three carbon atoms.

Propane: CH₃CH₂CH₃, alkane molecule, completely saturated and contains no double bonds

Propene: CH₃CH=CH₂, alkene molecule, single degree of unsaturation and contains one double bond

Propyne: CH₃C≡CH, alkyne molecule, two degrees of unsaturation and contains one triple bond
