Question

The general formula of an alkene is

• A. CnH2n
• B. CnH2n-2
• C. CnH2n+2
• D. CnHn

Answer 1

Answer:

A. CnH2n

• Alkenes are unsaturated hydrocarbons that contain at least one carbon-carbon double bond C=C.

• Their general chemical formula is C_nH_2n, where $n$ represents the number of carbon atoms.

• C_nH_2n-2is the general formula for alkynes (hydrocarbons with a triple bond).

• C_nH_2n+2is the general formula for alkanes (saturated hydrocarbons with single bonds only).
