Often asked: What Is The Electron-Pair Geometry For P In Pf6-?

For PF6- its electron domain geometry is an octahedral, its molecular geometry is also octahedral. Octahedral domain geometry is where six atoms are symmetrically arranged around a central atom.

What is the the shape molecular geometry of PF6 -?

The VSEPR model for [PF6] – is Octahedral.

What is the electron pair of geometry?

Electron pairs are defined as electrons in bonds, lone pairs, and occasionally a single unpaired electron. The various geometries are shown in the graphic on the upper left. Tetrahedral Electron Pair Geometry Examples: In methane, ammonia, water and hydrogen fluoride, the electron pair geometry is tetrahedral.

What is the oxidation number of P in PF6?

Oxidation number of P in is +6.

What is the hybridization of the P atom in PF6?

The hybridization of the P atom in PF−6 P F 6 − is sp3d2 s p 3 d 2 and the geometry is octahedral.

How many lone pairs are in PF6?

For hexafluorophosphate, [PF6], there are six bonded groups and so no lone pairs. This anion is useful in synthesis since it often aids the crystallization of bulky cations by providing a reasonable size match for the cation.

How many valence electrons are around the phosphorus atom in the Lewis structure of PF6?

Answer: So in the Lewis structure for PF6 its okay that we have 12 valence electrons around the Phosphorous atom.

What is the electron geometry for H2O?

H2O: Water has four electron groups so it falls under tetrahedral for the electron-group geometry. The four electron groups are the 2 single bonds to Hydrogen and the 2 lone pairs of Oxygen. Since water has two lone pairs it’s molecular shape is bent.

How do you write electron pair geometry?


  1. Write the Lewis dot structure of the molecule. That gives you the steric number (SN) — the number of bond pairs and lone pairs around the central atom.
  2. Use the SN and VSEPR theory to determine the electron pair geometry of the molecule.
  3. Use the VSEPR shape to determine the angles between the bonding pairs.
