Question

describe the shape of bf3 bh4- assign the hybridisation of boron in these species?​

Answer 1

Answer:

Hey Buddy here's ur answer

This triangular shape is formed by the overlap of three sp2 hybridised orbitals of boron with the sporbitals of three halogen atoms.

Boron is sp2 hybridised in BF3.

Boron-hydride ion (BH4-) is formed by the sp3 hybridisation of boron orbitals. Therefore, it is tetrahedral in structure.

Answer 2

Answer:

In BF3, boron is SP2 hybridized.

∴ shape of BF3 = planar.

In [BH4]–, boron is sp3 hybridized, thus the shape is tetrahedral.
