Question

what is hybridisation ? explain the formation of BF3 molecule with respect to hybridisation​

Answer 1

Explanation:

Hybridization is the idea that atomic orbitals fuse to form newly hybridized orbitals, which in turn, influences molecular geometry and bonding properties. Hybridization is also an expansion of the valence bond theory.1

BF3 has a boron atom with three outer-shell electrons in its ground state and three fluorine atoms containing seven outer electrons. ... In short, Boron needs 3 hybridized orbitals to make bonds with 3 atoms of F where the 2pz orbitals get overlapped with these hybridized sp2 orbitals and bonds are formed.

Answer 2

Answer:

Hybridization:

Hybridization can be defined as the idea that atomic orbitals fuse to form newly hybridized orbitals, which in turn, influences molecular geometry and bonding properties. Hybridization is also an expansion of the valence bond theory(VBT).

FORMATION OF BF3 MOLECULE:

General info:

BF3 has a boron atom with three outer-shell electrons in its ground state and three fluorine atoms containing seven outer electrons. Further, if we observe closely, one boron electron is unpaired in the ground state. FORMATION:

During the formation of this compound, the 2s orbital and two 2p orbitals hybridize. Only one of the empty p-orbital is left behind as the lone pair. In short, Boron needs 3 hybridized orbitals to make bonds with 3 atoms of F where the 2pz orbitals get overlapped with these hybridized sp2 orbitals and bonds are formed.

Points to ponder:

• The three hybridized sp2 orbitals are usually arranged in a triangular shape.
• BF3 molecule is formed by bonding between three sp2 orbitals of B and p of 3 F atoms.
• All the bonds in BF3 are sigma bonds
• The bond angle is 120° where all the atoms are in one plane. Each of them also makes an equilateral triangle.
