| Natural light was supplemented with high-intensity metal halide and sodium lamps suspended 1.3 m above the bench. |
| When a halogen combines with another element, the resulting compound is called a halide. |
| The halide retains the electron pair of the carbon-halogen bond when it leaves. |
| For instance, electronegativities in the halide sequence fluorine, chlorine, bromine, and iodine decrease from fluorine through iodine. |
| In this electrophilic aromatic substitution, the first electrophile is the Lewis acid that accepts the halogen from an alkyl halide. |
| The function of pyrazolone derivative in silver halide photographic paper is as a filter to prevent halation and irradiation. |
