Which reagent is used in breaking of diol?

Sodium periodate (NaIO4) breaks apart 1,2-diols (“vicinal” diols) to form aldehydes and ketones.

What is naio4 used for?

Sodium periodate (NaIO4), is a strong oxidizing agent mainly used for the oxidative cleavage of 1,2-diols (vicinal diols) forming aldehydes and ketones depending on the structure of the alcohol.

What is vicinal glycol?

A glycol, also known as a vicinal diol, is a compound with two -OH groups on adjacent carbons.

Which reagent is used for the oxidative cleavage of 1/2-diols?

Ch15: Oxidation cleavage of 1,2-diols. 1,2- or vicinal diols are cleaved by periodic acid, HIO4, into two carbonyl compounds. The reaction is selective for 1,2-diols. The reaction occurs via the formation of a cyclic periodate ester (see right).

Is naio4 acidic or basic?

Sodium periodate is an inorganic salt, composed of a sodium cation and the periodate anion. It may also be regarded as the sodium salt of periodic acid.

How do you make an aldehyde?

Making aldehydes

  1. Aldehydes are made by oxidising primary alcohols.
  2. The aldehyde produced can be oxidised further to a carboxylic acid by the acidified potassium dichromate(VI) solution used as the oxidising agent.
  3. To stop the oxidation at the aldehyde, you . . .

What is the function of HIO4?

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.

What is the formula of glycol?

Ethylene glycol/Formula

How do you get diol?

1,3-Diols can be prepared by hydration of α,β-unsaturated ketones and aldehydes. The resulting keto-alcohol is hydrogenated. Another route involves the hydroformylation of epoxides followed by hydrogenation of the aldehyde. This method has been used for 1,3-propanediol from ethylene oxide.

What is the formula for periodate?

Sodium periodate/Formula

What is an example of an aldehyde?

Aldehydes are given the same name but with the suffix -ic acid replaced by -aldehyde. Two examples are formaldehyde and benzaldehyde. As another example, the common name of CH2=CHCHO, for which the IUPAC name is 2-propenal, is acrolein, a name derived from that of acrylic acid, the parent carboxylic acid.
