Tetrabromoethane can be prepared from acetylene through a process of halogenation. Initially, acetylene (C₂H₂) is reacted with bromine (Br₂) in a non-polar solvent, resulting in the formation of dibromoethene (C₂H₂Br₂). This intermediate can then undergo further bromination to yield tetrabromoethane (C₂Br₄). The overall reaction involves the addition of bromine across the triple bond of acetylene, effectively saturating it with bromine atoms.
What else can I help you with?
How is acetylene gas prepared in the laboratory?
The usual laboratory method for making acetylene is by adding (dropwise) water to calcium carbide:CaC2 + 2 H2O → C2H2 + Ca(OH)2Calcium carbide is very cheap and available without restrictions in most countries.
What happens when a drop of water is added to calcium carbide in the presence of bromine solution?
Probable tetrabromoethane is formed.
Draw a reaction mechanism to show the formation of tetrabromoethane from two radicals?
The formation of tetrabromoethane from two radicals involves the reaction of ethylene (C₂H₄) with bromine radicals (Br·). Initially, a bromine molecule (Br₂) undergoes homolytic cleavage to generate two bromine radicals. These radicals then add to the double bond of ethylene, forming a bromoethyl radical intermediate. A second bromine radical then reacts with the bromoethyl radical, resulting in the formation of tetrabromoethane (C₂Br₄) as the final product.
What polymers are derived from acetylene gas is called polychloroprene?
Acetylene
What does acetone absorb in acetylene tanks?
Acetone is used in acetylene tanks to absorb and stabilize acetylene gas. It acts as a solvent that helps dissolve acetylene, allowing for safer storage at higher pressures. By absorbing acetylene, acetone prevents the gas from becoming too concentrated, which could lead to instability or detonation. This combination helps ensure the safe handling and transport of acetylene.

What is the geometry at the carbons in the acetylene?
Acetylene has a linear molecule.
What acetylene oxidation state?
Acetylene is a neutral compound.
Is acetylene a proplene based fuel?
Acetylene, C2H2, is a pretty simple hydrocarbon. http://en.wikipedia.org/wiki/Acetylene
How chloroform converted to acetylene?
Chloroform cannot be directly converted to acetylene. Acetylene is typically produced from calcium carbide through a reaction known as the acetylene generation process. In this process, water is added to calcium carbide to produce acetylene gas.
When was Acetylene - album - created?
Acetylene - album - was created in 2005.
What polymers are derived from acetylene gas is called polychloroprene?
Acetylene
Another name for acetylene?
Acetylene (C2H2) is also known as ethyne. It is the simplest alkyne.
What is the percentage of carbon in acetylene?
probably 92.3% of carbon is present in acetylene..
