What is the example of Organomercury?
Organomercury compounds such as aryl and alkoxy-aryl have been used in medicine, agriculture, and laboratory research. Their use in fungicides has been greatly reduced or eliminated. The major route of general population exposure to methylmercury is through the consumption of contaminated fish and fish products.
What are mercuric compounds?
Mercury(II) or mercuric compounds predominate. Mercury does not combine with oxygen to produce mercury(II) oxide, HgO, at a useful rate until heated to the range of 300 to 350 °C (572 to 662 °F). At temperatures of about 400 °C (752 °F) and above, the reaction reverses with the compound decomposing into its elements.
How is dimethylmercury made?
Their experiments show that dimethylmercury can be formed in the presence of iron sulfide particles, as well as other metal sulfide particles, via the reaction of two methylmercury molecules bound to the particle surface.
Why are Organomercury compounds are toxic?
Methylmercury is the most toxic of organomercurials, primarily due to its persistence (as demethylated inorganic mercury) within the central nervous system. Methylmercury that is not sequestered within the nervous system is demethylated and primarily excreted in the feces as inorganic mercury.
What is the difference between inorganic and organic mercury?
Inorganic mercury compounds are used in some industrial processes and in the making of other chemicals. Outside the United States, inorganic mercury salts have been used in cosmetic skin creams. Organic mercury compounds are formed when mercury combines with carbon.
What is organic mercury used for?
It is used in some thermometers, dental amalgams, fluorescent light bulbs, some electrical switches, mining, and some industrial processes. It is released into the air when coal and other fossil fuels are burned.
What molecules are made with mercury?
Mercury forms monovalent and divalent compounds with the halogens fluorine, chlorine, bromine and iodine. It also forms monovalent and divalent compounds with sulfur.

Is dimethylmercury a molecule?
Dimethylmercury is a methylmercury compound.
Where is dimethylmercury used?
For example, a major use of dimethylmercury is to calibrate certain research equipment such as Nuclear Magnetic Resonance (NMR). Inorganic mercury salts reportedly can be substituted for most of these operations.
What is the difference between elemental mercury and organic mercury?
What is organomercury chemistry?
Organomercury compounds are generated by many methods, including the direct reaction of hydrocarbons and mercury (II) salts. In this regard, organomercury chemistry more closely resembles organopalladium chemistry and contrasts with organocadmium compounds .
How many carbon atoms are present in organomercury?
Organomercury compounds contain at least one carbon bonded to a mercury atom, shown here. Organomercury refers to the group of organometallic compounds that contain mercury.
What is the toxicity of organomercury?
The toxicity of organomercury compounds presents both dangers and benefits. Dimethylmercury in particular, is notoriously toxic, but found use as an antifungal agent and insecticide. Merbromin and phenylmercuric borate are used as topical antiseptics, while Nitromersol is used as a preservative for vaccines and antitoxins.
How do you convert diethylmercury to organomercury?
A general synthetic route to organomercury compounds entails alkylation with Grignard reagents and organolithium compounds. Diethylmercury results from the reaction of mercury chloride with two equivalents of ethylmagnesium bromide, a conversion that would typically be conducted in diethyl ether solution.
