You may have actually heard about the chemical compound the lacks C-H bonds. Such compounds are recognized as ‘inorganic compounds’ together they room not the organic ones since of lacking Carbon. Boron trifluoride is the inorganic compound, and also its formula is BF3. That does no contain any color, and also it is a toxicity gas. It create white fumes in the moist air. If that is in the kind of a colorless liquid, that is an extremely soluble (dihydrate.)

Molecular Geometry of BF3

The geometry that molecule the BF3 is ‘Trigonal Planar.’ v the reference of Chemistry, ‘Trigonal Planar’ is a model with three atoms roughly one atom in the middle. It’s like peripheral atoms all in one plane, as all three of them are comparable with the 120° bond angles on every that makes them an it is intended triangle.

BF3 Lewis Structure


To know around BF3 Lewis structure, we need to calculate the total variety of valence electrons for the BF3 molecule. BF3 has a full of 24 valence electrons, which we have actually to collection around the main atom. Before completing the octets, don’t forget to determine how numerous valence electrons over there in Boron Trifluoride and also place castle accordingly.

Boron will be in ~ the center of the structure since of being the very least electronegative. It calls for six valence electron in its external shell. If we inspect the officially charges for the Boron Trifluoride Lewis structure, we will uncover that they room zero also though Boron only had actually six valence electrons.

How to attract BF3 Lewis Structure?

To draw a Lewis Structure, an initial of all, include electrons and also draw the connectivities. As discussed, right here there are 24 electrons. Then, add octets to the external atom and also extra electrons to the central atom. But, together we know, there space no extra electrons. (24 – 24 = 0)


One point to store in mind while illustration Lewis structure is the the Octet Rule can be violated in these three situations; but, we don’t should think about it each time together it is rare and these exceptions will certainly only occur when necessary.

Exception 1: If there is an odd variety of valence electrons like 3,5,7, etc.

Exception 2: If there space very few valence electrons

Exception 3: If there space too many valence electrons

Here, in this case, the main electron does not have any octet together it has actually six particles. So, try to add much more than one link to decision whether main atom can achieve an octet or not!


As you deserve to see, now it has an octet.

BF3 Hybridization

Hybridization means mixing atom orbitals into new hybrid orbitals. They room accommodating to define molecular geometry and also nuclear bonding properties. There space several species of hybridization like SP3, SP2, SP. BF3 is SP2 hybridization. Because that this molecule, it is SP2 due to the fact that one π (pi) bond is forced for the twin bond between the Boron and only 3 σ bond are formed per Boron atom. The atom S – orbitals and also P – orbitals in Boron external shell mix to type three equivalent SP2 hybrid orbitals.

BF3 Polarity

Polarity represents a separation of electric charge causing a molecule or its groups having an electrical dipole or multipole moment. If us talk about contradiction, then the answer is NO! BF3 is nonpolar. When the difference in electronegativity between the two atoms is less than 0.5, the is majority nonpolar.
