The general formula of an alkene is
ACnH2n
BCnH2n-2
CCnH2n+2
DCnHn
Answer:
A. CnH2n
Read Explanation:
Alkenes are unsaturated hydrocarbons that contain at least one carbon-carbon double bond C=C.
Their general chemical formula is CnH2n, where $n$ represents the number of carbon atoms.
CnH2n-2is the general formula for alkynes (hydrocarbons with a triple bond).
CnH2n+2is the general formula for alkanes (saturated hydrocarbons with single bonds only).
