Hint: To determine the hybridization of any compound, we must know the structure of that compound. Hybridization is defined as a concept of mixing two atomic orbitals having the same energy levels to give new degenerate orbitals.
Complete step by step answer:
The formula to calculate the hybridization of the central atom of the molecule is, . where V is the number of valence electrons of the central atom, X is the number of monovalent atoms attached to the central atom, C is the total cationic charge and A is the total anionic charge, H is the hybridization.
For, hybridization, the hybridization number (H) should be 5. These five orbitals are degenerate, that is their energies are the same but configurations are different.
In this hybridization there are a total of 5 orbitals which are, s, , , and . In the case of d subshell, the orbital takes part in this hybridization.
So, the correct answer is C.
Additional information:
For, the hybridization is,
For , the hybridization would be , so the geometry of is Trigonal bipyramidal. In this case, the central atom chlorine has 4 bond pairs and 1 lone pair, therefore, the shape is a see-saw. Due to this shape, it has a permanent dipole moment. The structure is shown below,
Remember that when a lone pair is present, then the molecular geometry will be the three-dimensional arrangement of the atoms without the lone pair. If there is no lone pair only bond pairs then the number of bond pairs can be equal to the hybridization number.
Note:In the case of hybridization there are a total of 6 orbitals which are, s, , , and . In the case of d subshell, the and orbitals take part in this hybridization. In the case of hybridization there is a total of 7 orbitals which are, s, , , and . In the case of d subshell, the , and orbitals take part in this hybridization.
Complete step by step answer:
The formula to calculate the hybridization of the central atom of the molecule is,
Hybridization number(H) | Hybridization | geometry |
2 | Sp | linear |
3 | | Trigonal planar |
4 | | tetrahedral |
5 | | Trigonal bipyramidal |
6 | | octahedral |
7 | | Pentagonal bipyramidal |
For,
In this
So, the correct answer is C.
