Difference Between Nitric Oxide and Nitric Oxide

Main difference - nitric oxide vs. nitric oxide (laughing gas)

Nitrogen oxide and laughing gas are nitrogen oxides. Nitrogen is a chemical element with atomic number 7 and it is a non-metal in the p-block of the periodic table of the elements. Nitrogen in its various oxides has different degrees of oxidation. The oxidation state is the number of electrons that a given atom can lose, gain or share with another atom. In nitric oxide, the nitrogen atom shares two electrons with an oxygen atom. Therefore, The oxidation state of nitrogen in nitric oxide is +2. In contrast, The oxidation state of nitrogen in nitrous oxide is +1. This is the main difference between nitric oxide and nitric oxide.

What is nitric oxide?

Nitric oxide is a nitrogen oxide with the chemical formula NO. A nitrogen atom is bound to an oxygen atom by a covalent bond. This means that the nitrogen atom and the oxygen atom share their unpaired electrons. Nitric oxide is a poisonous, colorless gas at room temperature and pressure.

The molar mass of this compound is 30 g / mol. The melting point of nitric oxide is -164 ° C and the boiling point -152 ° C. The nitric oxide molecule has a linear shape because only two atoms are bonded to each other. When the unpaired electrons are shared by nitrogen and oxygen, another unpaired electron is on the nitrogen atom. However, there are no other unpaired electrons on the oxygen atom. Then the unpaired electron is shared between the two atoms alone. Hence, the actual structure of the covalent bond is between a double bond and a triple bond. Then the bond length is 115 pm, which is a smaller distance between the two atoms than the expected value.

Nitric oxide can form nitrogen dioxide in the presence of oxygen. In water, however, nitric oxide reacts with oxygen and H.2O to nitrous acid (ENT2). When this gas is cooled it forms nitrogen oxide dimers (N.2O2). These are some of the main reactions caused by nitric oxide.

The oxidation state of nitrogen in nitric oxide is +2. This is because the oxidation state of oxygen is -2 and since the nitrous oxide molecule is a neutral compound, the oxidation state of nitrogen should be +2.

What is laughing gas (laughing gas)

Nitrous oxide is a nitrogen oxide with the chemical formula N.2O. The IUPAC name for nitrous oxide is Nitrous oxide. This gas is also called Nitrous oxide because this leads to insensitivity to pain that emanates from mild hysteria, sometimes from laughter.

The molar mass of this gas is 44 g / mol. At room temperature and pressure it is a colorless gas. The melting point of nitrous oxide is -90.86 ° C and the boiling point is -88.48 ° C. Then2An O molecule consists of two nitrogen atoms and one oxygen atom. The nitrogen atoms are bonded to each other and the oxygen atom is bonded to one of the two nitrogen atoms. If the chemical bond between these atoms is considered, N2O shows resonance. There are two main resonance structures for this molecule.

However, the actual structure is a hybrid of these structures.


Figure 4: Actual structure of nitric oxide

Nitrous oxide is considered an inert gas at room temperature and pressure and has very few chemical reactions. However, as the temperature is increased, the reactivity is also increased. For example, nitrous oxide reacts with NaNH at 187 ° C2 Manufacture of sodium azide (NaN3).

The oxidation state of nitrogen in nitrous oxide is +1. The oxidation state of oxygen is -2 and the nitrous oxide molecule is a neutral compound. Then the oxidation state of both nitrogen atoms should be +2 to balance the equation.

Oxidation state of nitrous oxide = 0

Oxidation state of the oxygen atom = -2

Therefore,

N2O = 2 (N) + (O)
0 = 2 (N) + (-2)
2 (N) = +2
(N) = +1
