(d) \(P F_{3}\)
ANSWER:Step 1 of 5
Here, we are going to find out electron and molecular geometries of each molecule.The bond angles can be calculated by using VSEPR theory. The repulsion between the electron groups of the internal atom determines the geometry of the molecule. The best possible geometry of the molecule is where electron groups have maximum separation between them. The VSEPR notation for a molecule is as follows
AXn, where "A" and "n" represent the central atom and the number of bonds with the central atom respectively.
When lone pair of electrons are present in a molecule, then the VSEPR notation will be AXnEn, where En is the number of lone pair of electrons present on the central atom.,
Electron group geometry depends on the number of electron groups around the central atom.
Molecular geometry of the molecule can be determined by electron groups as well as lone pairs of electrons.
