✓ Answer: A -C=C-
Alkenes are hydrocarbons characterized by a double bond between two carbon atoms, represented as -C=C-. The general formula for alkenes is CnH2n. Ethene (C2H4) is the simplest alkene and is widely used in the production of polymers. Alkanes (single bonds, -C-C-) follow the formula CnH2n+2. Alkynes (triple bonds, C≡C) follow the formula CnH2n-2.
