Nitrogen dioxide (NO2) is a molecule i m sorry contain 2 oxygen atom and also one nitrogen atom. Oxidation number of nitrogen atom can be uncovered by two methods, algebra method and observing framework of molecule. Oxidation number of nitrogen is essential to decision to whether NO2 deserve to be oxidized or reduced.

You are watching: Determine the oxidation state of nitrogen in no2

### Oxygen is much more electronegative than nitrogen. Therefore, electrons of N-O bonds are attracted towards oxygen atom.

Therefore, oxygen gets an ext electrons and we contact oxygen atoms it s okay a negative oxidation number. Also, nitrogen loser electrons and call, nitrogen atom get a positive oxidation number. ## Find oxidation number of nitrogen by observing the lewis structure

When you draw the best lewis framework of NO2, you can determine oxidation number of nitrogen atom NO2. Oxidation number because of bonds:
there is a twin bond and single bond approximately nitrogen atom. Those bonds space made with oxygen. Therefore, electron of bonds space attracted towards oxygen atom. early to dual bond and solitary bond, there space three bonds. Because that these three bonds, nitrogen has given three electrons to do those bonds. So, those three electrons are shed to nitrogen atom and also oxidation number will be three due to bonds. Oxidation number as result of charge: because there is +1 charge on nitrogen atom, it must be counted for overall oxidation number.

### overall oxidation number = Oxidation number because of bonds + Oxidation number due to charge

overall oxidation variety of nitrogen in NO2 = +3 + (+1) = +4

## Find oxidation variety of nitrogen in NO2 native algebra method

In this method, we room going to use known oxidation number in thhe molecule to find out unknown oxidation number of a atom in the exact same molecule. Normally oxygen"s most typical oxidation number is -2. But, nitrogen has actually so plenty of oxidation number from -3 come +5. Therefore, we space going to discover oxidation number of nitrogen using oxidation number of oxygen atoms (-2) .

NO2 is a neutral molecule. So, there is no as whole charge. Therefore, summation of oxidation number of all atoms in the molecule is zero.

### Oxidation number of nitrogen + summation of oxidation number of two oxygen atoms = 0

x + (-2)*2 = 0x = +4

Oxidation variety of nitrogen in NO2 is +4.

Questions inquiry by students

### What room the reaction of enhancing the oxidation number of nitrogen in NO2

Reaction in between nitrogen dioxide and also water: here oxidation variety of nitrogen is increased to +5 (HNO3) and also reduced come +2 (NO).

### Give part compounds which have oxidaion number greater than NO2 considering nitrogen

The only oxidation number i beg your pardon is higher than in NO2 is +5. As examples, HNO3 and N2O5 caan be given.

### Can i say NO2 is acidic by spring the oxidation variety of nitrogen?

We know nitrogen dioxide is acidic compound. Also, we understand when oxidation variety of an aspect is enhanced in a collection of the element"s oxides, acidic attributes are increased. Nitrogen"s best is oxidation number is +5. In nitrogen dioxide, oxidation number of nitrogen is +4 i m sorry is close come maximum oxidation variety of nitrogen. Therefore, NO2 should have acidic characteristics.

### What is the other oxide the nitrogen which has actually the same oxidation number as NO2

Dinitrogen tetroxide (N2O4) is the oxide the nitrogen which has actually the very same oxidation number as NO2.

### What can you decision by spring oxidation number of nitrogen in nitrogen dioxide?

Oxidation number of nitrogen in NO2 is +4. We know, nitrogen can display oxidation number from -3 to +5. Therefore, nitrogen atom in nitrogen dioxide has actually the capacity of oxidizing and also reducing. As an example, in the reaction the nitrogen dioxide and water reaction, nitrogen atom is oxidized come +5 oxidation state (nitric acid).

Also, due to the fact that oxidation variety of nitrogen is high optimistic value (+4), NO2 is an acidic oxide that nitrogen

### oxidation number of N in NO2

Oxidation variety of N in NO2 is +4. NO2 is an example for +4 oxidation state that nitrogen. early out +4 oxidation number, NO2 is an acidic gas. Usually, once an oxide of one element"s oxidation number increases, acidic features increases.
