Inorganic arsenic and its compounds, upon entering the food chain, are progressively metabolized through a process of methylation. [ 128 ] [ 129 ] For example, the mold Scopulariopsis brevicaulis produces trimethylarsine if inorganic arsenic is present. [ 130 ]
Organotin compounds are those with tin linked to hydrocarbons. The compound on the picture is trimethyltin chloride, an example of organotin compounds.. Organotin chemistry is the scientific study of the synthesis and properties of organotin compounds or stannanes, which are organometallic compounds containing tin–carbon bonds.
For example, the lithium salt of 4-methyl-2,6-di-tert-butylphenol reacts with SnCl 2 in THF to give the yellow linear two-coordinate compound Sn(OAr) 2 (Ar = aryl). [5] Tin(II) chloride also behaves as a weak Lewis acid, forming complexes with ligands such as chloride ion, for example: SnCl 2 + CsCl − → SnCl − 3
Illustrating the routes to such compounds, chlorine reacts with tin metal to give SnCl 4 whereas the reaction of hydrochloric acid and tin produces SnCl 2 and hydrogen gas. Alternatively SnCl 4 and Sn combine to stannous chloride by a process called comproportionation : [ 47 ]
Organochlorine chemistry is concerned with the properties of organochlorine compounds, or organochlorides, organic compounds that contain one or more carbon–chlorine bonds. [1] The chloroalkane class (alkanes with one or more hydrogens substituted by chlorine) includes common examples. The wide structural variety and divergent chemical ...
Tin(IV) chloride, also known as tin tetrachloride or stannic chloride, is an inorganic compound of tin and chlorine with the formula SnCl 4. It is a colorless hygroscopic liquid, which fumes on contact with air. It is used as a precursor to other tin compounds. [1]
Biomagnification is a process causing the concentration of a substance (crosses) to increase at higher levels of the food chain. In this scenario, a pond has been contaminated with toxic waste. Further up the food chain, the concentration of the contaminant increases, sometimes resulting in the top consumer dying.
Top diagram shows potentials at pH 0; bottom diagram shows potentials at pH 14. [5] Industrially, ammonia (NH 3) is the most important compound of nitrogen and is prepared in larger amounts than any other compound, because it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and ...
