Why glucose and other similar carbohydrates are oxidised fully by HIO4? $\ce {HIO4_ { (aq)}}$ requires the vicinal diols to have syn configuration, as it forms a cyclic periodate ester But glucose does not have syn configuration at C3, and if you consider cyclic forms of glucose it shouldn't oxidise fully at all because alternate hydroxy groups with anti configuration will be unreactive
Periodic acid cleavage of carbohydrates - Chemistry Stack Exchange Carbohydrates like glucose undergo cleavage by $\\ce{HIO4}$ and form respective products: five moles of formic acid and one mole of formaldehyde What is mechanism? What are the products when fructo
What is the formula name for HIO4? - Answers HIO4 is an iodine oxoacid widely referred to as periodic acid (in Dutch: Periodsaeure, and Ueberiodsaeure) and hyperiodic acid (as HIO4) It is also referred to as tetraoxoiodic acid, and by the
Oxidation of hydroxyl groups of glucose - Chemistry Stack Exchange Accordingly, the oxidation reaction of D-glucose with 5 equivalents of $\ce {HIO4}$ gives five equivalents of formic acid and one equivalent of formaldehyde (Figure A) An analogous degradation of D-fructose yields three equivalents of formic acid, two equivalents of formaldehyde, and one equivalent of carbon dioxide (Figure B):
Periodate oxidation of sugars - Chemistry Stack Exchange The reaction using $\ce {HIO4}$ is called Malaprade Reaction (Ref 1), while that involving $\ce {Pb (OAc)4}$ is called Criegee Reaction Malaprade Reaction is described as: The oxidation of adjacent diols with periodic acid or its salt in aqueous solution is generally known as the Malaprade reaction
How do you name the compound HIO4? - Answers HIO4 is known as periodic acid It is a strong oxidizing agent and is used in organic chemistry for reactions involving oxidation of alcohols to carbonyl compounds
Periodic acid oxidation of carbonyls? - Chemistry Stack Exchange $\ce {CH2OH-CHOH-CH2OH -> [HIO4]CH2O + HCOOH + CH2O + 2H2O}$ Apparently, there are similar reactions by 2,3-dihydroxypropanal, and also by the straight chain form of fructose The first two reactions involve doing the Malaprade reaction on molecules with adjacent alcohol and aldehyde groups, and the last one involves doing it on a ketone
What is the oxidation number of HIO4? - Answers What is the ternary acid HIO4? HIO4 is known as periodic acid It is a strong oxidizing agent and is used in organic chemistry for reactions involving oxidation of alcohols to carbonyl compounds
Acid strengths for HBrO4 vs HIO4, and HBr vs HI We know that $\ce {HI}$ is a stronger acid that $\ce {HBr}$ because $\ce {I}$ is a much larger atom But then, I read somewhere that $\ce {HBrO4}$ is stronger than $\ce {HIO4}$, because in this case it's electronegativity that plays the important role How do you know whether to use size or EN as a guideline for comparing strengths of acids bases?
