About binary compound A halide is a binary compound , of which one part is a halogen atom and the other part is an chemical element element or radical chemistry radical that is less electronegative or more electropositive than the halogen, to make a fluoride , chloride , bromide , iodide , or astatide compound. Many salt chemistry salt s are halides. All Group 1 element Group 1 metals form halides compounds which are white solids at room temperature. A halide ion is a halogen atom bearing a negative charge. The halide anion s are fluoride F sup sup , chloride Cl sup sup , bromide Br sup sup , iodide I sup sup and astatide At sup sup . Such ions are present in all ionic bonding ionic halide salts. Tests Halide compounds such as Potassium chloride KCl , Potassium bromide KBr and Potassium iodide KI can be tested with silver nitrate solution, AgNO sub 3 sub . The halogen will react with Ag sup sup and form a precipitate , with varying colour depending on the halogen Silver I fluoride AgF No Precipitate Silver chloride AgCl White Silver bromide AgBr Creamy Pale Yellow Silver iodide AgI Green Yellow For organic compounds containing halides, the Beilstein test is used.

Vinyl chloride is one such substance. Vinyl halides are very useful synthetic intermediates due to the vast number of reactions that make use of them. These include conversion to vinyl Grignard reaction Grignard reagents , elimination to give the corresponding alkyne , and most importantly their use in coupling reaction cross coupling reactions e.g. Suzuki reaction Suzuki Miyaura coupling , Stille reaction Stille coupling , Heck reaction Heck coupling , etc. . As a result, there is a large number of reactions to form vinyl halides, which includes the reaction of vinyl organometallic species with halogens, and the Takai olefination Takai and Wittig reaction Wittig olefination reactions.

Geminal halide hydrolysis is an organic reaction . The reactants are a geminal halide dihalide and water or a hydroxide . The reaction product is a ketone or an aldehyde . The first part of the reaction mechanism consists of an ordinary nucleophilic aliphatic substitution to produce a gem halohydrin . The remaining halide is a good leaving group and this enables the newly created Hydroxyl hydroxy group to revert to a carbonyl group expelling the halide. Similar reactions involving any strong electronegative functional group , such as a nitrile , in place of the halide also occur. In a similar fashion 1,1,1 trihalides are hydrolyzed to carboxylic acid s in the haloform reaction .

The ceramic discharge metal halide CDM lamp, mostly referred to as Cermic metal halide lamp CMH , is a relatively new source of light that is a variation of the old high pressure mercury vapour lamp . The discharge is contained in a ceramic tube. During operation, the temperature of this ceramic tube can exceed 1200 kelvin s. The ceramic tube is filled with mercury element mercury , argon and metal halide salt s. Because of the high wall temperature, the metal halide salts are partly vaporized. Inside the hot plasma physics plasma , these salts are dissociated into metallic atoms and iodine. The metallic atoms are the main source of light in these lamps, creating a bluish light that is close to daylight with a color rendering index CRI color rendering index of up to 96. The exact correlated color temperature and CRI depend on the specific mixture of metal halide salts. There are also warm white DCM lamps, with somewhat lower CRI 78 82 which still give a more clear and natural looking light than the old mercury vapour and sodium vapour lamps when used as street lights, besides being more economical to use. CDM lamps use one fifth of the power of comparable tungsten incandescent light bulb s for the same light output 80 117 lm W and retain colour stability better than most other gas discharge lamps. Applications for these lamps include television and film making as well as shop lighting, digital photography , street and architectural lighting .

On contact with water almost instant hydrolysis occurs with the precipitation of silver Ag powder. Crystal structure Ag sub 2 sub F adopts the anti CdI sub 2 sub crystal structure , i.e. the same structure as cadmium iodide , CdI sub 2 sub , but with Ag sup sup in the I sup sup positions and F sup sup in the Cd sup 2 sup positions. ref name williams cite journal author A Williams title Neutron powder diffraction study of silver subfluoride journal Journal of Physics Condensed Matter J.
