Nitrogen trifluoride is a chemistry compound v chemical formula NF3. That is classified together an inorganic compound. That exists together a colorless gas having a musty smell at room temperature. It is non-flammable in nature. Many students may have actually a question about whether NF3 is polar or not. In this article, us will comment on this and also will cover its properties and applications.

So, Is NF3 Polar or Nonpolar? NF3 is polar in nature as result of the visibility of lone pair ~ above nitrogen atom causing a distorted form of NF3 molecule and also the difference between the electronegativity of fluorine(3.98) and nitrogen(3.04) causes polarity in N-F bond and result in a no zero dipole moment of the whole molecule.

Nitrogen trifluoride exist in the form of colorless gas v musty odor in ~ the standard problems of temperature and pressure.

It was very first synthesized by the scientist otto Ruff in the year 1903 by the process of electrolysis the a molten mixture that hydrogen fluoride and also ammonium fluoride.

It is well-known to be lesser reactive than other halides the nitrogen choose nitrogen trichloride, nitrogen tribromide, etc.

It is manufactured straight by reaction nitrogen v fluorine and also commercially that is supplied in pressurized cylinders.

Nitrogen trifluoride gas is taken into consideration as a solid greenhouse gas (causing an international warming).

The molecule of nitrogen trifluoride is made up of 1 nitrogen atom and 3 fluorine atoms. The nitrogen atom is a central atom surrounded by three fluorine atoms.

The molecule that NF3 is composed of a total of 8 valence electrons. Nitrogen atom has 5 electron in that outermost shell and also requires 3 electrons to complete its octet.

And, Fluorine has actually 7 valence electrons in its outermost shell and requires a single electron to complete its octet.

Accordingly, all 3 fluorine atoms share one electron that the nitrogen atom to get stabilize leaving behind one lone pair ~ above the nitrogen atom.

The shape of the Nitrogen trifluoride is formed as trigonal pyramidal comparable to the shape of the ammonia molecule(NH3).

The electronegativity that Nitrogen is 3.04 and that that fluorine is 3.98. Because of this difference, the N-F bond guarantee polarity in it.

Being more electronegative, the fluorine atom attractive the bonded electron pair slightly an ext towards it and also gains a partial an unfavorable charge.

In return, Nitrogen gains a partial confident charge ~ above it.

As a result, the dipole moment across al the three N-F shortcut rises in the downwards direction in the direction of fluorine atom. And one dipole of lone pair originates in the direction of lone pair in the increase direction.

The net dipole moment of the entire molecule transforms out to it is in 0.24 D.

What space Polar and Nonpolar Molecules?

The molecules are hosted with the different species of interatomic forces like ionic, covalent, metallic, and hydrogen bonds.

Covalent and also ionic bonds space the strongest amongst all the bonds.

Polar Molecules: the molecule that have non zero dipole minute are well-known as polar molecules. These molecules have actually unequal charge circulation on its atoms.

The covalent bond created by two atoms is claimed to it is in polar if the atoms differ in their electronegativity.

This is because an ext electronegative atom attracts the bonded electron pair slightly an ext towards the side and gains partial negative charge whereas other atom profit partial positive charge.

Few examples of together molecules room OF2, NH3, CO, etc. You can check out the factor for the polarity that NH3.

Nonpolar Molecules: The molecule that have actually zero dipole moment are said to it is in nonpolar. The atoms within these molecules have actually equal charge distribution on them as result of which no polarity wake up in them.

The two atoms that room covalently bonded form a nonpolar shortcut if the electronegativity the both atoms is the same.

Few instances of such molecules room PCl5, SO3, Cl2, etc. You can inspect out the factor for the non-polarity that SO3.

Why is NF3 a polar molecule?

Nitrogen trifluoride is composed of 1 nitrogen and 3 fluorine molecules that differ in their electronegativity.

The 3 fluorine atoms type covalent bonds through the nitrogen atom by share one electron of each various other to acquire stabilized.

One lone pair stays on the nitrogen atom that causes repulsion between lone pair and bond pairs bring about the bent shape (trigonal pyramidal) that the NF3 molecule.

As a result, the three dipoles across the N-F shortcut originate in the downward direction and also one dipole originates towards upward direction as result of the visibility of lone pair.

The net dipole minute of the whole molecule comes the end to it is in 0.24 D.

The dipole moment of a molecule steps the degree of polarity in it.

The form of the molecule is similar to that of ammonia.

Factors affect polarity the a molecule

Electronegativity: The electronegativity of an atom is the strength to tempt the external inspection electron pair in the direction of its side.

In a molecule, if there is a difference in between the electronegativity of two atoms then there exist a polarity in that bond.

The polarity the a molecule is directly proportional to the difference in the electronegativity of atoms.

Dipole Moment: The dipole moment of a molecule is the measure of its polarity. The polarity the a molecule is directly proportional come the dipole that a molecule.

It is the product that the charge on atoms and also the distance in between them.

D = Q * R

Geometrical shape: The form of a molecule is crucial parameter to check whether a substance is polar or not.

Generally, symmetrically shaped molecules room nonpolar in nature. Conversely, the asymmetrically shame molecules tend to it is in polar.

Below is the photo of the geometrical form of the nitrogen trifluoride molecule.


Hybridization the NF3

The term hybridization of a molecule is the concept of mix of two electrons orbitals at the same power level to type a new form of orbital.

This intermixing of orbitals is based ~ above quantum mechanics.

As discussed above, the molecule the NF3 has actually distorted pyramidal structure thus it has actually sp3 hybridization.

Many of girlfriend may frequently mistake it to be sp2 together it has actually only 3 atoms bonded to it. However it need to be understood that NF3 also consists that one lone pair ~ above nitrogen atom as result of which it has actually sp3 hybridization.

For detailed information, you should read out the write-up written top top NF3 lewis structure, hybridization, molecule geometry.

Properties the NF3

It exists together a colorless gas with a musty odor at the standard problem of temperature and also pressure.At a temperature of 15° C and pressure of 1 atm, the density of this gas is 3.003 kg/m3.The molecule mass that the NF3 molecule is 71.00 g/mol.Its melting point is −207.15 °C or −340.87 °F and also its billing point is −129.06 °C or −200.31 °F.It is taken into consideration a solid greenhouse gas ie; causes an international warming.

Uses of NF3

It is offered for various industrial processes.Nitrogen fluoride problem is offered for cleansing the PECVD chambers.This is also used in deuterium fluoride and also hydrogen fluoride lasers.


Nitrogen trifluoride consists of 3 fluorine and 1 nitrogen atoms that differ in their electronegativity. The form of this molecule is trigonal pyramidal as result of the presence of lone pair top top the nitrogen atom.

Fluorine being more electronegative traction the external inspection electron bag slightly more towards that side and also gains a partial an unfavorable charge because of which polarity rises in the molecule.

Therefore, the dipole minute of the NF3 molecule is 0.24 D that makes NF3 a polar molecule.
