| Many alkyl halides, alcohols, or alkenes can be reacted with benzene in the presence of certain catalysts to give an alkyl benzene. |
| These groups are the silicate minerals, carbonate minerals, oxides, sulfides, and halides. |
| But methyl bromide and methyl chloride, unlike the CFCs in halides have both human and natural sources. |
| The chemical reactivity of titanium to the halides is similarly exhibited by its combination with their acids. |
| The acetylides are also strong bases and in reactions with secondary or tertiary alkyl halides elimination reactions can occur instead. |
| In a similar way, both hydroxide ions and water molecules may act as nucleophiles by reacting with alkyl halides to produce alcohols. |
