test for alkanes and alkenes lab report

>> CHM220 Addition lab *Adapted from Experiments for General, Organic and Biochemistry, Experiment 24 by Bettelheim and Landesberg Experiment: Reactions of alkanes, alkenes, and cycloalkenes* Purpose: To investigate the physical properties, solubility, and density of some hydrocarbon. They can be liquids, for example, benzene.

/Length 4867 The reaction between bromine and alkenes is an example of a type of reaction called an, . %���� Aim The purpose of carrying out this experiment is to identify Alkanes and Alkenes by their reactions … �d�Ô The test for unsaturation is demonstrated.

The bromine is decolourised because a colourless dibromo compound forms. The slideshow shows this process. This allows us to tell alkenes apart from alkanes using a simple chemical test. stream Jump to Page .
