What happens when glycol reacts with periodic acid?

Oxidative Cleavage of Vicinal Diols with Periodic Acid: Mechanism. In this reaction, an intermediate cyclic ester is formed between periodic acid and the glycol derivative and water is eliminated concurrently. Unlike the periodic acid oxidation, the reaction with lead tetraacetate also takes place in non-aqueous media.

What does HIO4 reagent do?

Periodic acid (HIO4) is a reagent that cleaves the carbon-carbon bonds in a sugar through oxidation. Periodic acid attacks the vicinal diols in carbohydrates and oxidizes these groups to form carbonyl compounds.

Which reagent is used in breaking of diol?

Sodium Periodate (NaIO4) Cleaves 1,2-Diols (“Vicinal” Diols) To Aldehydes And Ketones. Sodium periodate (NaIO4) breaks apart 1,2-diols (“vicinal” diols) to form aldehydes and ketones.

What is naio4 used for?

NaIO4 is used in organic chemistry to cleave diols to produce two aldehydes.

What happens when glycerol is treated with periodic acid?

Periodic acid is a selective oxidising agent. When glycerol reacts with periodic acid, two moles of formaldehyde is obtained due to the two end carbons and 1 mole of formic acid is obtained due to the central carbon.

What happens when glycol reacts with lead tetraacetate Mcq?

What happens when glycol reacts with lead tetraacetate? Explanation: Lead tetraacetate is used cleave a carbon-carbon bond in a glycol. This reaction is useful in the formation of ketones and aldehydes and involves a favourable five membered cyclic intermediate.

What is Malaprade reagent?

From Wikipedia, the free encyclopedia. In organic chemistry, the Malaprade reaction or Malaprade oxidation is a glycol cleavage reaction in which a vicinal diol is oxidized by periodic acid or a periodate salt to give the corresponding carbonyl functional groups.

What is Lemieux reagent?

The conversion of an olefin into two individual aldehydes by means of an oxidative cleavage of a carbon-carbon double bond with osmium tetraoxide-sodium periodate is known as the Lemieux–Johnson oxidative cleavage and the combination of osmium tetraoxide and sodium periodate is referred to as Lemieux–Johnson reagent.

What happens when glycerol is treated with hio4?

Two molecules of formaldehyde and one molecule of formic acid.

What happens when glycerol is heated with oxalic acid?

Now, if glycerol is heated with oxalic acid at 530 K, glycerol will get converted into allyl alcohol as shown below: This high temperature gives allyl alcohol.
