You may have actually heard about the chemical compound that lacks C-H bonds. Such compounds are known as ‘inorganic compounds’ as they space not the necessary ones due to the fact that of lacking Carbon. Boron trifluoride is the not natural compound, and its formula is BF3. It does no contain any color, and also it is a toxicity gas. It creates white fumes in the moist air. If it is in the kind of a colorless liquid, the is really soluble (dihydrate.)

Molecular Geometry of BF3

The geometry the molecule the BF3 is ‘Trigonal Planar.’ v the recommendation of Chemistry, ‘Trigonal Planar’ is a version with 3 atoms approximately one atom in the middle. It’s like peripheral atoms every in one plane, as all three of lock are comparable with the 120° bond angles on every that renders them an equilateral triangle.

BF3 Lewis Structure


To know around BF3 Lewis structure, we have to calculate the total variety of valence electrons for the BF3 molecule. BF3 has a total of 24 valence electrons, i m sorry we have actually to collection around the central atom. Prior to completing the octets, nothing forget to determine how numerous valence electrons over there in Boron Trifluoride and also place lock accordingly.

Boron will be in ~ the facility of the structure because of being the very least electronegative. It needs six valence electron in its external shell. If we check the formal charges for the Boron Trifluoride Lewis structure, we will find that they room zero even though Boron only had actually six valence electrons.

How to draw BF3 Lewis Structure?

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


One point to keep in psychic while illustration Lewis framework is that the Octet Rule have the right to be violated in these 3 situations; but, us don’t must think about it every time together it is rare and also these exceptions will only occur when necessary.

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

Exception 2: If there are very couple of valence electrons

Exception 3: If there room too numerous valence electrons

Here, in this case, the central electron does no have any type of octet as it has six particles. So, try to add more than one shortcut to decision whether central atom can accomplish an octet or not!


As you deserve to see, currently it has actually an octet.

BF3 Hybridization

Hybridization means mixing atomic orbitals into new hybrid orbitals. They space accommodating to describe molecular geometry and also nuclear bonding properties. There space several species of hybridization favor SP3, SP2, SP. BF3 is SP2 hybridization. For this molecule, it is SP2 due to the fact that one π (pi) link is forced for the double bond between the Boron and also only three σ bond are created per Boron atom. The atom S – orbitals and also P – orbitals in Boron external shell mix to kind three tantamount SP2 hybrid orbitals.

BF3 Polarity

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