What is the name of the following compound OsO4?
Osmium tetroxide
Why does Lemieux-Johnson's reagent have advantage over oxygen?
Maybe it has something to do with "Lemieux-Johnson oxidation" but this does NOT involve oxygen, rather sodium periodate is involved as oxidant in dihydroxylation of an alkene (olefine) by osmium tetroxide, OsO4, followed by oxidative cleavage by sodium periodate, NaIO4, to produce two molecules of aldehydes or ketones.If this is not the desired answer please rephrase your question more specific.
What are the uses of the metal osmium?
Osmium, a platinum group metal, reacts slowly with atmospheric oxygen at room temperature giving to OsO4. On heating it burns. Bulk metal doesn't react with boiling aqua regia. Osmium powder reacts with nitric acid and boiling concentrated sulfuric acid. On heating osmium reacts also with fluorine, chlorine, phosphorus, tellurium etc. On melting with alkalies in the presence of oxidizing agents it turns into salts of osmic(VI) acid H2OsO4.
What is the formula for OsO4?
Osmium tetroxide is the chemical compound with the formula OsO4.
What is the chemical formula Osmium tetroxide?
It is OsO4
What is the name of the compound that has the formula OsO4?
Osmium Tetraoxide
What is the name of the following compound OsO4?
Osmium tetroxide
How alkene convert in to oxalic acid?
alkene treat with OsO4. 1,2 diols are formed. which is then oxidized to give oxalic acid
Can you make a compound out iridium and osmium?
Yes they will both react with fluorine and oxygen to form compounds. OsO4 is particularly useful even though toxic
What is the product of E-2-Pentene with OsO4 pyridine followed by aqueous NaHSO3?
(2S,3S)-2,3-Pentanediol and (2R,3R)-2,3-Pentanediol

How is osmium used for microscopy fingerprint detection?
Osmium tetroxide (OsO4) is used in fingerprint detection. It is a strong oxidant and it reacts with unsaturated carbon-carbon bonds in lipids which are found in fatty tissue. It fixes biological membranes in tissue samples and also stains them. Osmium atoms have a very high electron density so such stained samples have a very high image contrast in electron microscopy.
What are the dangers of osmium?
Osmium is considered to be a toxic metal. One compound of osmium is particularly poisonous, OsO4 which is a very volatile oxide, it is molecular which is unique amongst metal oxides, with a melting point of 400C. It causes pulmonary edema and can stain the cornea causing blindness.
How can you get glycrin from propene?
Propene + Br2 + hv ==> 3-Bromo-1-propene (free radical halogenation - allylic position is halogenated only)3-bromo-1-propene + OsO4 ==> 1,2 dihydroxy-3-bromo propane (or, you can also use MCPBA to create the epoxide and open it with mild acid or base, or you can use Br2 and H2O to create the halohydrin... lots of options here)1,2 dihydroxy-3-bromo propane + NaOH ==> 1,2,3 trihydroxy propane (glycerin aka glycerol)
Give an example of osmium?
Osmium is a naturally occurring chemical element with the symbol Os and atomic number 76. It is a hard, brittle, bluish-white transition metal. An example of osmium is osmium tetroxide (OsO4), which is a highly toxic and volatile compound used in various chemical reactions, particularly in organic synthesis and staining biological samples for electron microscopy.
