The general formula for the alkanes is C n H 2n+2 (where n is the number of carbon atoms in the molecule). The table shows four alkanes, their molecular formulae, displayed formulae and structural ...

alkenes and cycloalkanes are examples of homologous series. A homologous series is a group of chemicals which have similar chemical properties and can be represented by a general formula.

The rapid disappearance of the amber color of the bromine at room temperature is characteristic of reaction with alkenes. (colorless) (purple) (colorless ...
