Hybridization in PtCl₄2-
Hybridization is a concept in chemistry that helps us understand the arrangement of electrons in the orbitals of an atom. In the case of PtCl₄2-, which is a coordination complex, the central atom is platinum (Pt) surrounded by four chloride ions (Cl-).

Hybridization of Pt in PtCl₄2-
- The Pt atom in PtCl₄2- undergoes sp³ hybridization.
- In sp³ hybridization, one s orbital and three p orbitals of the Pt atom combine to form four equivalent sp³ hybrid orbitals.
- These hybrid orbitals have a tetrahedral arrangement around the Pt atom, with an angle of 109.5° between them.

Explanation of the Hybridization Process
- The s orbital and three p orbitals of Pt hybridize to form four sp³ hybrid orbitals.
- Each hybrid orbital contains one electron, and these orbitals overlap with the 4 Cl- ions to form Pt-Cl bonds.
- The hybridization allows for the formation of four Pt-Cl bonds in a tetrahedral geometry around the Pt atom.

Conclusion
In PtCl₄2-, the Pt atom undergoes sp³ hybridization to form four equivalent sp³ hybrid orbitals. This hybridization allows for the formation of four Pt-Cl bonds in a tetrahedral arrangement around the Pt atom. Understanding the hybridization in PtCl₄2- helps in predicting its molecular geometry and chemical properties.
