The geometry of the molecule with sp3d2 hybridised central atom isSquare planarTrigonal bipyramidalOctahedralSquare pyramidal

Break Down the Problem

1. Identify the hybridization of the central atom.
2. Understand the molecular geometry associated with sp³d² hybridization.

Relevant Concepts

1. Hybridization: sp³d² refers to the mixing of one s orbital, three p orbitals, and two d orbitals.
2. Molecular Geometry:
   • sp³d² typically indicates an octahedral geometry, but when considering lone pairs or other factors, it may result in different arrangements.

Analysis and Detail

1. An octahedral geometry arises from a central atom that is surrounded by six bonding pairs of electrons, giving a bond angle of 90 degrees.
2. If there are lone pairs, this geometry can modify. For example, if there are one or more lone pairs present in an octahedral arrangement, it can lead to a square pyramidal or square planar shape.

Verify and Summarize

1. In a pure octahedral geometry (all bonding pairs), the angle is 90 degrees, confirming its classification as octahedral.
2. If modified due to lone pairs, the geometry could be square pyramidal or square planar depending on the number of lone pairs.

Final Answer

The geometry of a molecule with an sp³d² hybridized central atom is Octahedral if there are no lone pairs. If there is one lone pair, it becomes Square Pyramidal, and with two lone pairs, the geometry is Square Planar.
