What is ethylene dibromide used for?
Ethylene dibromide is a potent mutagen used as an industrial solvent, gasoline lead scavenger, and fumigant.
Why was EDB banned?
The U.S. Environmental Protection Agency has ordered the immediate emergency suspension of ethylene dibromide (EDB) as a soil fumigant for agricultural crops. Laboratory test results have shown EDB to be a carcinogen and mutagen and that it causes reproductive disorders in test animals. …
What does EDB stand for in agriculture?
Much attention has recently been focused on the chemical ethylene dibromide (EDB). This chemical has been widely used in leaded gasoline, and has also been used to treat grains, citrus and other crops. It has been found in foods and in groundwater.
Is ethylene dibromide bad for humans?
Ethylene dibromide is extremely toxic to humans. The chronic (long-term) effects of exposure to ethylene dibromide have not been well documented in humans. EPA has classified ethylene dibromide as a Group B2, probable human carcinogen.
What is GEM dibromide?
Gem-dihalides are those in which two halogen atoms are attached on the same carbon atom.
What is ethylidene bromide?
ethylene bromide (C2H4Br2), also called ethylene dibromide or 1,2-dibromoethane, a colourless, sweet-smelling, nonflammable, toxic liquid belonging to the family of organohalogen compounds. Ethylene bromide is prepared by the reaction of ethylene with bromine.
How do fumigants act on stored grain How do we use ethylene dibromide?
Answer:Fumigation is a method of pest control that completely fills an area with gaseous pesticides—or fumigants—to suffocate or poison the pests within. This method also affects the structure itself, affecting pests that inhabit the physical structure, such as woodborers and drywood termites.

What is a geminal dichloride?
Geminal refers to the relationship between two atoms or functional groups that are attached to the same atom. Propylidene chloride is the common name of IUPAC compound 1,1−dichloropropane.
What is vicinal Dihalide?
Vicinal dihalides, compounds that have halogens on adjacent carbons, are prepared by the reaction between a halogen and an alkene. The simplest example is the reaction between ethylene and chlorine to give 1,2-dichloroethane (ethylene dichloride).
How do we get ethyl bromide?
(i) Preparation of ethyl bromide from ethyl alcohol: By treating the ethyl alcohol (C2H5OH) with phosphorus tribromide (PBr3), we get ethyl bromide (C2H5Br). It is a substitution reaction because the hydroxyl group (OH) of the alcohol is substituted by the bromide ion (Br).
