Chemistry - Hydrocarbon Question with Solution | TestHub

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

For an aliphatic, non-cyclic alkene with one double bond, the general molecular formula is ${\text{C}}_n{\text{H}}_{2n}$, where $n$ is the number of carbon atoms.

${\text{C}}_n{\text{H}}_{2n+2}$ is the general formula for alkanes.

${\text{C}}_n{\text{H}}_{2n-2}$ is the general formula for alkynes.

Answer: ${\text{C}}_n{\text{H}}_{2n}$
