Mechanism of reaction between 2-butene and chloroform in presence of potassium t-butoxide?
In the reaction between 2-butene and chloroform in the presence of potassium t-butoxide, the chlorine from chloroform attacks the terminal carbon of 2-butene, resulting in the formation of a new bond between carbon and chlorine. This leads to the formation of tetrachloroethane. The potassium t-butoxide serves as a base to facilitate the reaction by abstracting a proton from the chloroform molecule.
What else can I help you with?
Why chloroform is used in the assay of potassium iodide?
Chloroform is used in the assay of potassium iodide because it forms a complex with iodine liberated from potassium iodide in presence of acid, and this complex has a pink color that can be easily detected. This color change helps in monitoring the reaction and determining the concentration of potassium iodide in the sample.
Why is SnI4 soluble in chloroform?
SnI4 is soluble in chloroform because chloroform is a nonpolar solvent, while SnI4 has a nonpolar nature due to the presence of polarizable iodine atoms. This nonpolar-polar interaction allows for the dissolution of SnI4 in chloroform.
What happens when you add iodine crystal and chloroform?
iodine is soluble in CHCl3. Liquid become purple in color.
Is toluene more polar than Chloroform?
yes toluence is more polar than chloroform
What does bromine in chloroform test for?
Bromine in chloroform tests for the presence of unsaturation in a compound. It reacts with alkenes or alkynes to form red or brown coloration in the chloroform layer. This test is known as the bromine test.

Why tricyanomethane is stronger than chloroform?
Tricyanomethane is stronger than chloroform due to the presence of highly electronegative cyano groups, which can stabilize the negative charge better than the chloroform molecule. This enhanced stabilization allows tricyanomethane to act as a stronger acid than chloroform.
How is The presence of a refuge is an important mechanism?
The presence of a refuge is an important mechanism that stabilizes otherwise unstable predator-prey interactions.
Why lithium acetylacetonate soluble in chloroform?
Lithium acetylacetonate is soluble in chloroform due to the presence of polar groups (such as the acetylacetonate ligands) in the molecule that enable interactions with the polar solvent molecules of chloroform. These interactions help to stabilize the resulting solution, leading to the solubility of lithium acetylacetonate in chloroform.
Which is more stronger in dissolving lipids chloroform or hexane and why?
Chloroform is stronger in dissolving lipids compared to hexane because chloroform has a higher polarity due to the presence of electronegative chlorine atoms. This polarity allows chloroform to interact more effectively with lipid molecules, which generally have polar and nonpolar regions, making them more soluble in chloroform than in hexane.
How do you test a pure chloroform?
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.
Why Acetone and chloroform are soluble in each other?
Acetone and chloroform are both polar solvents due to the presence of a carbonyl group (in acetone) and a chloro group (in chloroform), which allows them to form hydrogen bonds with each other. This intermolecular attraction leads to their solubility in each other.
What is formed when chloroform combines with nitrogen?
When chloroform combines with nitrogen in the presence of heat or sunlight, phosgene gas is formed. Phosgene is a toxic gas used in chemical warfare and as a chemical intermediate in industry. It is important to handle chloroform and nitrogen safely to avoid the formation of phosgene.
