Question

Ethylene dibromide is :
(A)- $C{{H}_{3}}C{{H}_{2}}Br$
(B)- $Br-C{{H}_{2}}-C{{H}_{2}}-Br$
(C)- $C{{H}_{3}}-CHB{{r}_{2}}$
(D)- \[C{{H}_{2}}=CHBr\]

Answer 1

Hint: Ethylene dibromide is also known as Ethylene bromide or Glycol bromide. The IUPAC name of ethylene dibromide is 1,2-Dibromoethane.

Complete step by step answer:
-Ethylene dibromoethane abbreviated as EBD, is an organobromine compound which is a dense colorless liquid with a faintly sweet odor.
-Ethylene dibromide is produced in traces in the sea by algae and kelp.
-The combustion of ethylene dibromide produces a corrosive gas that is hydrogen bromide.
-The chemical formula of ethylene dibromide is ${{C}_{2}}{{H}_{4}}B{{r}_{2}}$ or $Br-C{{H}_{2}}-C{{H}_{2}}-Br$
So, the correct answer is “Option B”.

-Ethylene dibromide is produced by a classic halogen addition reaction. In this, ethylene gas is reacted with bromine.
$C{{H}_{2}}=C{{H}_{2}}+B{{r}_{2}}\to BrC{{H}_{2}}-C{{H}_{2}}Br$

Additional Information:
-Ethylene dibromide has been used as a pesticide in soil and on various crops for ages.
-Ethylene dibromide in organic synthesis is also used as a reagent and a source of bromine to brominates carbanions and to activate magnesium for certain Grignard reagents.
-Ethylene dibromide is also used as an intermediate for the preparations of dyes, resins, waxes and gums.

Note: - Ethylene dibromide is a chemical compound that is acutely toxic, irritant to health and environmentally hazardous too.
-This chemical substance can be absorbed into the body by inhalation of its vapor through the skin and by ingestion.
- Ethylene dibromide on short-term exposure can irritate the eyes, skin, and respiratory tracts. It can also affect the livers and kidneys.
-Ethylene dibromide on long term or repeated exposure can cause skin dermatitis. This substance has carcinogenic, mutagenic, toxic, and teratogenic effects on human health. A male and female who have breathed 1,2-dibromoethane, their offsprings have shown changes in the brain and behavior. Long term exposure to EBD can cause impairment of reproduction by damaging sperm cells.
