Question

Give the hybridization for the br in bro4⁻.

Answer 1

The hybridization for the Br in BrO4⁻ is $sp^{3}$. So, the correct option is (e).

In chemistry, the idea of combining atomic orbitals to create new hybrid orbitals (with different energies, shapes, etc., than the component atomic orbitals) is known as orbital hybridisation (or hybridization). These new hybrid orbitals are suitable for the pairing of electrons to form chemical bonds in valence bond theory.

Because more directional hybridised orbitals result in higher overlap when creating bonds, stronger bonds are formed, which favours the hybridization of orbitals. When hybridization takes place, this leads to more stable molecules.

One s orbital and three p orbitals combine to form four $sp^{3}$ orbitals, each of which has a 25% s character and a 75% p character. This process is known as $sp^{3}$ hybridization. Anytime an atom is surrounded by four groups of electrons, this kind of hybridization is necessary.
