NaIO2 chemical name


NaIO2 compound name?


The compound NaIO2 is known as sodium periodate.

Sodium periodate (NaIO2) is an inorganic compound composed of sodium (Na) cations and periodate (IO4-) anions. It is an oxidizing agent commonly used in various chemical reactions.

The periodate ion (IO4-) is a polyatomic ion made up of one iodine (I) atom bonded to four oxygen (O) atoms. The chemical formula for the periodate ion is IO4-, and it has a -1 charge to maintain electrical neutrality in the compound. Sodium periodate is formed when sodium cations (Na+) combine with periodate anions (IO4-) in a 1:1 ratio.

The primary application of sodium periodate is its use as an oxidizing agent. It can cleave vicinal diols (adjacent hydroxyl groups) in compounds to form aldehydes or ketones. This property is valuable in organic chemistry for selectively breaking specific carbon-carbon bonds in diols to generate aldehyde or ketone functional groups.

Here’s an example of how sodium periodate is used to oxidize a diol to an aldehyde or ketone:

Let’s take the diol compound ethylene glycol (HO-CH2-CH2-OH) as an example:

  1. Sodium periodate (NaIO2) reacts with ethylene glycol (HO-CH2-CH2-OH).
  2. The sodium periodate cleaves the carbon-carbon bond between the two hydroxyl groups (OH) in ethylene glycol, resulting in two aldehyde functional groups: CHO and CHO.
  3. The final products of the reaction are glyoxal (OHC-CHO) and formaldehyde (HCHO).

The reaction can be represented as follows:

HO-CH2-CH2-OH + NaIO2 → OHC-CHO + HCHO + NaI + H2O

It’s important to handle sodium periodate with care, as it is an oxidizing agent and can react vigorously with certain substances. It is typically used under controlled conditions in a laboratory setting by experienced chemists.
