Introduction In the study of organic chemistry, the organic compounds which are made up of carbon and hydrogen are called hydrocarbons. Search inside document . … They can be low-melting solids and waxes, for instance, polystyrene. 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. Complete combustion needs plenty of air. /Length 4867 Bromine water is an orange solution of bromine. >> Try the given examples, or type in your own This has the effect of ‘saturating’ the molecule, and will turn an alkene into an alkane. Jacob Solanki 03.13.15 Tests for Alkanes and Alkenes Purpose of Experiment: To differentiate chemical reactivity Formal Report, Carboxylic Acid and Derivatives . Hydrocarbons di er primarily in the functional group. cannot. The activity can be extended to include testing the samples with a 1% potassium manganate(vii) solution. Academia.edu is a platform for academics to share research papers. The reaction between bromine and alkenes is an example of a type of reaction called an addition reaction. x��7���+�orM��N��%�Mm����. They are obtained primarily from natural sources such as coal, petroleum, and natural gas. ���� Hypothesis Alkenes are much more reactive than alkanes. B�i'��Lw problem solver below to practice various math topics. Alkanes produces less colour intensity and less soot given off during combustion test compared to alkenea. To compare the chemical reactivity of an alkane, an alkene, and an aromatic compound.
