Halide



A halide is a binary compound, of which one part is a salts are halides. All Group 1 metals form halides with the halogens and they are white solids.

A halide ion is a halogen atom bearing a negative charge. The halide anions are ionic halide salts.

Halides in organic chemistry

In covalently bonded to a halogen X.

Pseudohalides resemble halides in their charge and reactivity; common examples are Isocyanide, CN-, etc.[1]

A chemical test for the detection of halogen in chemical substances is the Carius halogen method.

Dihalides are commonly used in the synthesis of cyclic alkanes.

Halides in lighting

high-pressure sodium lamps. Metal halide lamps are also commonly used in greenhouses or in rainy climates to supplement natural sunlight.

HID (High-intensity discharge) lamps however, contribute highly to light pollution. Sodium-vapor are favored for this reason.
