Introduction

Alkanes are hydrocarbons with only single bonds between the atoms. Saturated hydrocarbon is the other term for it. They are used as fuels because they are non-reactive and also do not conduct electricity. For this reason they do not form hydrogen bonds and are insoluble in solvents such as water while alkenes are hydrocarbons that contain at least one carbon-to-carbon double bond. Unsaturated hydrocarbons are the other term for alkenes. They are stable compounds, but more reactive than alkanes due to the presence of carbon-carbon bond.

Objectives:
* To know if potassium permanganate solution will show reactions with oil and fat samples. * To determine if the results of the performed experiment are saturated or unsaturated and alkane or alkene if the samples are mixed with potassium permanganate.

Hypothesis:
If the fats and oils will be added by potassium permanganate solution then we will know if it is an alkane or an alkene.

Materials and Methods

* We obtained 2 full droppers (medicine dropper) of each oil sample, such as coconut oil, canola oil, corn oil, linseed oil and castor oil and placed it in different test tubes each. Different droppers were used to gather each sample. * We then melted the solid samples; butter, lard, and margarine using the warm water bath provided by the laboratory and tested them as liquids. * After getting all the samples needed, we added one dropper full of potassium permanganate solution to each samples and with the use of stirring rod, we stirred it then was covered with stoppers.
