Reaction between periodic acid and glucose?
HIO4 cleaves C-C bonds between vicinal -OH groups so you get the malaprade reaction: HOCH2(CHOH)4CHO + 4 HIO4 ------> H2C=O + 4 HCOOH + 4 HIO3 Only 4 HIO4 molecules required to cleave..........
Can you make glycerin safely at home?
Glycerin is HOCH2-CHOH-CH2OH. It is commercially available - you can probably buy it bulk from online. It is not worth making yourself (but can be synthesized via the saponification of lipids). Are you asking if you can make nitroglycerin at home (which can be made from glycerin)? Nitroglyercin is EXTREMELY explosive. It is shock sensitive, which means that simply bumping it with your hand can cause it to explode. It is also heat sensitive (heat causes it to explode) and the process of making it is exothermic (heat releasing), so the very process of making it can cause it to explode. You should NEVER EVER EVER attempt to make nitroglyercin at home.
How is glycosidic linkage formed?
An example of a glycosidic linkage is the linking of two molecules of glucose, which form the disaccharide Maltose. Another example is the linkage of glucose and fructose, which forms sucrose, otherwise known as simple table sugar.
What is the mechanism for the Tollens' test?
Tollen's test is an old oxidation reaction in which the oxidizing agent is a complex cation, diamminesilver(I), (NH3)2Ag+, and the reducing agent is probably the anion of an aldehyde hydrate, which for formaldehyde could be written as HOCH2-O(-). The mechanism is probably not known; a literature search I just performed turned up no immediately useful hits. Historically, the two front-runners for the likely mechanism are single-electron-transfer (SET) and hydride abstraction by diaminosilver(I). These two processes turn up in most oxidation mechanisms involving an electron-rich CH bond (as the one in the aldehyde hydrate) and an electron-poor metal cation. SET involves direct transfer of an electron from the molecular orbital closely tied to the C-H bond about to be broken, to the silver ion. Hydride abstraction involves a favorable collision between the silver ion and the aldehyde hydrate in which H- (the hydride ion) is transferred to the silver, leaving HOCH(+)-O(-) behind, which is essentially just a resonance structure for formic acid, HOCHO. The fate of the newly formed silver-hydride bond is almost certainly the release of a hydronium ion, leaving behind a neutral silver ion. The mechanism would have to explain why benzaldehyde reacts almost instantly, while sugars and branched-chain aldhydes react slowly, for example, as well as why siilver carbonate, Ag2CO3, supported on celite oxidizes alcohols to aldehydes and stops (J. Org. Chem, 1974, vol 39, p. 523), but Tollen's test conditions oxidize aldehydes (not alcohols) to acids, among other experimental observations.
Draw the structural formula for glucose?
Glucose can be in several different forms. Dry or powdered glucose is in a chain form, but more often glucose is represented in a hexagonal form. Further specification of alpha or beta glucose may be required as this can alter the chemical properties to some extent.
