The boron atom of BBr3 has
maks197457 [2]

Answer: The boron atom of BBr_3 has three hybrid orbitals

Explanation: Hybridization of the molecule can be calculated by:

Hyb=\frac{1}{2}(V+H-C+A)     .....(1)

where,

V =  number of valence electrons in the central metal atom

H = number of monovalent atoms

C = cationic charge

A = anionic charge

Here, electronic configuration of B = 1s^22s^22p^1

Number of valence electrons = 3

Number of monovalent atoms = 3

Cationic charge = 0

Anionic charge = 0

Putting these values in equation 1, we get

Hyb=\frac{1}{2}(3+3-0+0)=3

As the Hybridization is 3, which means that boron has 3 hybrid orbitals.
