WebJun 27, 2024 · In the mercury-thiol bond, the mercury is a Lewis acid and the thiol is a Lewis base. Sulfur is a "soft" atom, it's relatively large and not very electronegative. Mercury is also soft due to its very large size. Soft acids prefer to react with soft bases, and vice versa. The oxygen of alcohols, however, is hard. microwave hutch cherry wood

WebEthylmercury (C 2 H 5 Hg +) is a substituent of compounds: it occurs as a component of compounds of the formula C 2 H 5 HgX where X = chloride, thiolate, or another organic group.Most famously X = the mercaptide group of thiosalicylic acid as in thiomersal.In the body, ethylmercury is most commonly encountered as derivatives with a thiolate attached … Akin to the chemistry of alcohols, thiols form sulfides, thioacetals, and thioesters, which are analogous to ethers, acetals, and esters respectively. Thiols and alcohols are also very different in their reactivity, thiols being more easily oxidized than alcohols. Thiolates are more potent nucleophiles than the corresponding alkoxides.
