Ethyl bromide, also known as bromoethane, is a chemical compound belonging to the haloalkanes group. It is a colorless, volatile liquid at room temperature and has a high refractive index. It is used in organic synthesis and as a refrigerant.

Chemical Properties[edit | edit source]

Ethyl bromide is a halogenated hydrocarbon. It is a volatile, colorless liquid that is slightly soluble in water but miscible with most organic solvents. It has a sweet, ether-like odor. The chemical formula for ethyl bromide is C2H5Br, and its molecular weight is 108.97 g/mol.

Synthesis[edit | edit source]

Ethyl bromide is synthesized through the reaction of ethanol with hydrobromic acid, a process known as nucleophilic substitution. The reaction is exothermic and proceeds rapidly at room temperature.

Uses[edit | edit source]

Ethyl bromide is primarily used as an alkylating agent in organic synthesis. It is also used as a refrigerant, a blowing agent for foams, and a soil fumigant. In the past, it was used as an anesthetic.

Safety[edit | edit source]

Exposure to ethyl bromide can cause irritation to the eyes, skin, and respiratory tract. It is also a central nervous system depressant and can cause dizziness, confusion, and in severe cases, unconsciousness. Chronic exposure can lead to liver and kidney damage.
