BF3 polarity

to understand thenon-polar nature of BF3, we need to understand its structure.
The boron trifluoride molecule has one boron atom and three fluorine atoms. Boron has valence 3 and fluorine has valence 7. The fluorine atom, on the other hand, contains threelone pairs of electrons, therefore the molecular structure is balanced and symmetrical.
The following table provides details about the electronic configuration of the constituent atoms and their valence electrons.

Flúor (F)1s22s22p57

VE me BF3 = VEs me 1 atom B + VE in 3 atoms of F
VE= 1(3)+3(7) =24 electrons

Boron trifluoride contains only six valence electrons and is one of the rare second-period covalent compounds that defies theory.octet rule. There are three linked groups, so there are no lone pairs. Six electrons implies three pairs of electrons and, as a result, a trigonal geometry.

Boron Trifluoride Properties

  • Boron trifluoride is a colorless, toxic gas.
  • boyfriend3the molar mass is 67.805 g mol-1.
  • Boron trifluoride is soluble in water.
  • It is also soluble in sulfuric acid and organic solvents such asbenzene, carbon tetrachloride, sulfur dioxide and chloroform.
  • BF3 is used in the manufacture of adhesives and sealing chemicals, as well as lubricants and lubricant additives.
  • It is also used as a catalyst in alkylation, esterification andcondensation reactions.
  • BF3 is polar or non-polar:BF3 is non-polar

What is polarity?

Polarity is caused by the distribution of electric charge between the atoms connected by the bond.
It has been found, for example, that the bonds between atoms of different elements are electrically unequal. For example, in hydrogen chloride, the H atom has a slightly positive charge, while the Cl atom has a slightly negative charge.
Small electrical charges on different atoms are called partial charges, and the presence of partial charges means that a polar bond has occurred.

Examples of Polar Molecules

Some examples of polar molecules are:

  • Water (H2O)
  • Ethanol
  • Ammonia
  • SO2 (Enxofre Dioxide).

Examples of Nonpolar Molecules

  • Carbon dioxide
  • Benzene
  • Carbon tetrachloride
  • Methane
  • Ethylene

CO no polarity2

Carbon dioxideIt is a nonpolar molecule that contains polar bonds.
CO2is a linear molecule and the C=O are polar bonds.
The central carbon has a net positive charge, while the two surrounding itoxygenshave a net negative charge.
Due to the linearity of the carbon dioxide molecule, these two bond dipoles cancel each other out.
As a result, the molecule as a whole has no dipole.

Lewis CO2 structureshow CO2Molecules composed of two oxygen atoms and one carbon atom that are covalently bonded. Two oxygen atoms are located on the sides of a carbon atom, where they share electrons and form bonds. Since the carbon atom is the least electronegative, it is present in the center of the molecule.

BF3 Molecular Geometry

BF3 molecular geometry is 'planar trigonal'. According to Chemistry, a 'Trigonal Planar' model has three atoms surrounding an atom in the center. They are like peripheral atoms all in one plane, because all three are similar with bond angles of 120° in each, forming an equilateral triangle.


Some of the summary points are listed below:

  • The answer to the question“Is the BF3 polar or non-polar?”is that BF3 is nonpolar.
  • Boron trifluoride (BF3) is a nonpolar inorganic chemical compound.
  • there is a total of24 valence electronsto BrF3lewis structure
  • The BF3 molecular geometry is a trigonal plane.
  • Boron trifluoride is a colorless gas with a terrible, suffocating odor.

frequent questions

Some of the frequently asked questions are given below. If you have any questions, feel free to post a comment.

1. What is the difference between Ammonia and Boron Trifluoride?

Boron trifluoride is an inorganic compound with the chemical formula BF3, while ammonia is an inorganic compound with the chemical formula NH3. The main distinction between ammonia and boron trifluoride is that ammonia is a polar molecule while boron trifluoride is a nonpolar molecule.

2. What is the structure of BF3?

The structure formed in the plane shows that the molecular geometry of BF3 is trigonal planar (the central atoms are surrounded by three-terminal atoms). This geometry forms an equilateral triangle with an angle of 120 degrees on each side.

3. Is the BF3 polar or non-polar?

BF3 is a nonpolar compound. In BF3, the central Boron atom has sp2 hybrid orbitals, resulting in an empty p orbital on the Bron atom and trigonal planar molecular geometry. Since the Boron-Fluorine bonds are all 120 degrees apart, any liquid dipoles in that plane cancel. Although each B-F bond is polar, the net dipole moment is zero because the sum of the bond vectors cancels out.

4. Is hydrogen sulfide (H2S) polar or nonpolar?

Hydrogen sulfide (H2S) is a colorless gas with a strong “rotten egg” odor.
The difference in the electronegativity values ​​of the hydrogen (2.2) and sulfur (2.58) atoms makesH2S is a slightly polar molecule.
Furthermore, the existence of two lone pairs on opposite sides of the two hydrogen atoms makes the molecule more polar and results in the curved geometric structure of H2S. Check the full article“Is H2S polar or nonpolar?”.

5. Is SiCl4 polar or nonpolar?

SiCl4 (silicon tetrachloride) is a nonpolar molecule. Since the four chemical bonds between silicon and chlorine are evenly distributed,SiCl4 is nonpolar.A polar covalent bond is a type of covalent bond intermediate between pure covalent bonds and ionic bonds. When the difference in electronegativity between the anion and the cation is between 0.4 and 1.7, such bonds occur.
Check the full article“Is SiCl4 polar or nonpolar?”.

6. Is NH3 a polar or non-polar molecule?

Ammonia (NH3) is a polar molecule.Since the molecule contains three N-H bond dipoles that do not cancel. In each bond, nitrogen is more electronegative than hydrogen. This uneven distribution of charges between the nitrogen and hydrogen atoms makes NH3 a polar molecule.

7. Oxidation number of NH3?

ONH3 oxidation numberis the sum of the individual oxidation numbers of the nitrogen (oxidation number = -3) and hydrogen (oxidation number = 1) atoms is zero.

8. What is nitrogen trifluoride gas?

Nitrogen trifluoride (NF3)It is an odorless and colorless gas. When inhaled, it is extremely poisonous. Containers may violently explode if exposed to fire or heat for an extended period of time.

9. What is perchloric acid used for?

Perchloric acid (HCLO4)It is used to separate potassium from sodium in many laboratory tests and industrial processes. It is also used as an oxidizing agent, especially in the determination of chromium in steel, ferrochrome, chromite, and leather.

10. Is SO2 an ionic or covalent compound?

When the electronegativity difference between two elements is between 0 (two elements of the same element bonded) and 1.69, a covalent bond (almost an ionic bond) is created. The element oxygen has an electronegativity of 3.5 in a SO2 molecule while the element sulfur has an electronegativity of 2.6; the difference in electronegativity between the two elements is 0.9. As a result, SO2 is a covalent molecule that is also somewhat polar.


This article answers the question“BF3 is polar or non-polar”and BF3 molecular geometry.
We hope that after reading the article, you can understand the nonpolar nature of BF3 and its molecular structure of BF3. If you have any questions on this topic, feel free to post a comment.
