Can you give examples and name them?
Alkanes are saturated hydrocarbons, i.e. they have no carbon-carbon double bonds. They take on the suffix -ane and have the empirical formula CnH2n+2. For example: Ethane is H3C-CH3 (C2H6).
Alkenes are hydrocarbons with at least one carbon-carbon double bond. They take on the suffix -ene and have the empirical formula CnH2n. For example: Ethene is H2C=CH2 (C2H4). For multiple double bonds, the suffix may be -diene, -triene, etc.
Alkynes are hydrocarbons with at least one carbon-carbon triple bond. They take on the suffix -yne and have the empirical formula CnH2n-2. For example: Ethyne is HC≡HC (C2H2). As alkenes, they may be -diynes, etc.
