Question

formation of BF3 molecule​

Answer 1

BF3 is SP2 hybridization. For thismolecule, It is SP2 because one π (pi) bond is required for the double bond between the Boron and only three σ bonds are formed per Boron atom. The atomic S – orbitals and P – orbitals in Boron outer shell mix to form three equivalent SP2 hybrid orbitals.

Answer 2

The geometry of molecule of BF3 is ‘Trigonal Planar.’ With the reference of Chemistry, ‘Trigonal Planar’ is a model with three atoms around one atom in the middle. It’s like peripheral atoms all in one plane, as all three of them are similar with the 120° bond angles on each that makes them an equilateral triangle.
