Indicate the type of hybrid orbitals used by the central atom in tef4
Explanation : While we are considering the molecule of Te it forms trigonal bi-pyramidal structure which undergoes sd hybridisation. The lone pair of Te takes the equatorial position in the molecular structure.
The type of hybrid orbitals used by the tellurium could be found via the following formula:
In this case, tellurium has six valance electrons and four monovalent bonds (those four fluorines), thus:
Such result, indicates a hybridisation which accounts for one ‘s’, three ‘p’ and one ‘d’ orbitals of almost equal energy which give five identical and degenerated hybrid orbitals arranged in trigonal bipyramidal symmetry.
the answer is b: sp3d
Explanation: BrF3 has a Bent T shaped structure with Br as a central atom bonded with three F atoms (three bond pairs) and two lone pairs. Hence , the hybridization would be sp3d. Br atom has 7 electron in its outer most shell. After the bond formation of BrF3 molecule we have 3 bond pairs+ 2 lone pairs
