| The group III and IV elements, on the other hand, tend to form covalent halides. |
|
| The acetylides are also strong bases and in reactions with secondary or tertiary alkyl halides elimination reactions can occur instead. |
|
| Many alkyl halides, alcohols, or alkenes can be reacted with benzene in the presence of certain catalysts to give an alkyl benzene. |
|
| The chemical reactivity of titanium to the halides is similarly exhibited by its combination with their acids. |
|
| But methyl bromide and methyl chloride, unlike the CFCs in halides have both human and natural sources. |
|
| In a similar way, both hydroxide ions and water molecules may act as nucleophiles by reacting with alkyl halides to produce alcohols. |
|
| These groups are the silicate minerals, carbonate minerals, oxides, sulfides, and halides. |
|
| The oxides, hydrides, and halides are volatile covalent compounds that have low melting points. |
|
| In covalent halides, such as carbon tetrachloride, the bonding electrons are localized in the carbon-chlorine bonds of the individual molecules. |
|
| Both black and white and color film photochemistry relies predominantly on the photosensitivity of microcystalline grains of silver halides. |
|
| Alkyl halides are produced by adding hydrogen halides across the double bonds. |
|
| Two men discovered that in the presence of Lewis acids, alkyl halides will alkylate benzenes. |
|
| In elimination reactions, larger molecules expel smaller molecules like water, hydrogen halides, carbon dioxide and other diatomic gases to form new substances. |
|
| The methyl halide can be produced by reacting methanol with phosphorous halides, hydrogen halides, or, in the case of methyl chloride, thionyl chloride. |
|
| The halides all contain halogen elements, such as chlorine and fluorine. |
|
| Primary alkyl halides react with aqueous NaOH or KOH mainly to primary alcohols in nucleophilic aliphatic substitution. |
|
| Mori et al developed a fast-curing adhesive using silyl groups and a Lewis acid such as metal halides or boron halides as curing catalysts. |
|
| The other three silver halides are highly insoluble in aqueous solutions and are very commonly used in gravimetric analytical methods. |
|
| The decreased volatility is attributed to the molecular polarity induced by the halides, which induces intermolecular interactions. |
|
| The ferrous halides typically arise from treating iron metal with the corresponding hydrohalic acid to give the corresponding hydrated salts. |
|
|
|
| Iron reacts with fluorine, chlorine, and bromine to give the corresponding ferric halides, ferric chloride being the most common. |
|
| It is often used for gravimetric analysis, exploiting the insolubility of the silver halides which it is a common precursor to. |
|
| The use of silver nitrate and silver halides in photography has rapidly declined with the advent of digital technology. |
|
| Photochromic lenses include silver halides, so that ultraviolet light in natural daylight liberates metallic silver, darkening the lenses. |
|
| If the alloying metal is sufficiently reductive, plutonium can be added in the form of oxides or halides. |
|
| White silver nitrate, AgNO3, is a versatile precursor to many other silver compounds, especially the halides, and is much less sensitive to light. |
|
| The first route is a synthesis involving the nucleophilic aromatic displacement of carbonyl-activated halides by phenoxide anions, in which a diaryl ether linkage is obtained. |
|
| The photosensitivity of the silver halides allowed for their use in traditional photography, although digital photography, which does not use silver, is now dominant. |
