This causes a smoky flame. Alkenes have a functional group C=C – the part of the molecule that takes part in reactions. Alkanes, in contrast, do not have a functional group and are less reactive ...

UV light splits the bromine molecule into two reactive radicals ... The rapid disappearance of the amber color of the bromine at room temperature is characteristic of reaction with alkenes. (colorless ...

The table shows the first four alkenes, their molecular formulae, displayed formulae, structural formulae as well as a drawing of their ball-and-stick constructional models.
