Chemistry no2
WebNO2 is a neutral molecule with odd electrons and can combine with other NO2 molecules and exist as a dimer N2O4. We can also write NO2 as NO2- ion as it contains a coordinate covalent bond and is called a nitrate ion. Nitrogen has one odd electron and is an example of an odd electron species. WebJan 8, 2024 · Nitrite [NO 2] – is a polar molecular ion. It consists of one N-O and one N=O polar bond having an electronegativity difference of 0.4 units between an oxygen and a nitrogen atom.
