Tetrafluoroethane (a haloalkane) is a colorless liquid that boils well below room temperature (as seen here) and can be extracted from common canned air canisters by simply inverting them during use. The haloalkanes (also known as halogenoalkanes or alkyl halides ) are alkanes containing one or more halogen substituents. [ 1 ]

In Pakistan, hot salt frying is mostly used by street vendors to cook corn. Rock salt is preheated in a wok. Either the whole corn or individual kernels are buried in the salt and occasionally turned. In India, [1] this technique is used by street vendors selling shelled peanuts, chickpeas or popcorn cooked in salt heated in an iron wok.

Bromoethane, also known as ethyl bromide, is a chemical compound of the haloalkanes group. It is abbreviated by chemists as EtBr (which is also used as an abbreviation for ethidium bromide). This volatile compound has an ether-like odor.
Haloalkanes are diverse in their properties, making generalizations difficult. Few are acutely toxic, but many pose risks from prolonged exposure. Some problematic aspects include carcinogenicity and liver damage (e.g., carbon tetrachloride). Under certain combustion conditions, chloromethanes convert to phosgene, which is highly toxic.
Traditionally Grignard reagents are prepared by treating an organic halide (normally organobromine) with magnesium metal. Ethers are required to stabilize the organomagnesium compound.
