unsaturation in a molecule
Shaking bromine water with chloroform is a common test to detect the presence of unsaturation in a compound. If an alkene is present, it will react with bromine to decolorize the bromine water, forming a colorless solution due to the addition of bromine across the double bond. This test is known as the bromine test for unsaturation.
The chloroform layer will turn purple or violet in color due to the formation of the organic bromine compound when NaBr reacts with Cl2 in water and then extracted into chloroform during the test.
Yes, bromine can react with chloroform to form bromoform and hydrogen chloride. This reaction is a halogenation reaction where bromine substitutes the hydrogen atoms in chloroform.
Ethanol does not react with bromine.
To test for pure chloroform, you can perform a few different methods: Measure its boiling point which is around 61.2 degrees Celsius. Perform a density test to determine if it matches the known density of chloroform, which is about 1.48 g/cm3 at 20 degrees Celsius. Use a chloroform test strip or reagent to confirm the presence of chloroform based on a color change or reaction.
Bromine in chloroform typically tests for the presence of alkenes or aromatic compounds. Bromine will react with the double bond or aromatic ring to form a dibromo compound, resulting in a color change from red-brown to colorless. This test is commonly known as the bromine test.

Astatine is slightly soluble in chloroform due to its similar halogen properties. However, its solubility is lower compared to other halogens like iodine or bromine.

One simple chemical test to distinguish between benzene and hexane is the Bromine test. Benzene will not react with bromine in the absence of a catalyst, while hexane will readily react with bromine to form a colorless product.
You can test the purity of chloroform by using techniques such as gas chromatography or infrared spectroscopy to analyze its composition and identify any impurities present. Additionally, purity can also be assessed by determining the density and refractive index of the chloroform sample and comparing these values to known values for pure chloroform.
Salkowsk's test is a test for cholesterol;when concentrated sulfuric acid is added to a chloroform solution of cholesterol, the chloroform layer shows a red to blue color and the acid layer shows a green fluorescence.
Positive Bromine tests are for unsaturated compounds that have double or triple bonds. Decane has a single bond, so the test will be negative.
