∙ 9y agoAnything with six electron groups, keep in mind an electron group is a bonded atom or an electron pair, is an octahedral.
Anything in an octahedral and a lone pair is the square pyramidal geometry.
So all angles between the atoms are a little less than 90 degrees and the angle of the electron pair is greater than 90.

The molecular geometry of a molecule can be determined using the VSEPR theory. VSEPR (Valence Shell Electron Pair Repulsion) Theory: The basic premise of this simple theory is that electron pairs (bonding and nonbonding) repel one another; so the electron pairs will adopt a geometry about an atom that minimizes these repulsions. Use the method below to determine the molecular geometry about an atom. Write the Lewis dot structure for the molecule. Count the number of things (atoms, groups of atoms, and lone pairs of electrons) that are directly attached to the central atom (the atom of interest) to determine the overall (electronic) geometry of the molecule. Now ignore the lone pairs of electrons to get the molecular geometry of the molecule. The molecular geometry describes the arrangement of the atoms only and not the lone pairs of electrons. If there are no lone pairs in the molecule, then the overall geometry and the molecular geometry are the same. If the overall geometry is tetrahedral, then there are three possibilities for the molecular geometry; if it is trigonal planar, there are two possibilities; and if it is linear, the molecular geometry must also be linear. The diagram below illustrates the relationship between overall (electronic) and molecular geometries. To view the geometry in greater detail, simply click on that geometry in the graphic below. Although there are many, many different geometries that molecules adopt, we are only concerned with the five shown below.

Bent, like water.
since it has a total of two atoms , its molecular shape is linear with bond angles of 180 degree.

square planar
trigonal planar
This is a linear molecule.
The molecular geometry characterized by 109.5 degree bond angles is tetrahedral. This geometry occurs when a central atom is bonded to four surrounding atoms with no lone pairs on the central atom. An example of a molecule with this geometry is methane (CH4).
The conclusion of molecular geometry is the three-dimensional arrangement of atoms that determines a molecule's shape. By understanding the arrangement of atoms, scientists can predict a molecule's physical and chemical properties.
The molecular geometry of HOCN is trigonal planar. This is because the molecule has a central carbon atom with three surrounding atoms (one oxygen, one hydrogen, and one nitrogen) arranged in a flat, triangular shape. This configuration leads to a trigonal planar molecular geometry.
Silicon Tetrafluoride has a tetrahedral molecular geometry. That means there are 4 F atoms around the central atom Si.

Electron geometry describes the arrangement of electron pairs around a central atom in a molecule, based on the total number of electron pairs (bonding and nonbonding). Molecular geometry, on the other hand, describes the arrangement of atoms, taking into account only the positions of the atoms. They will not be the same when there are lone pairs of electrons on the central atom. In such cases, the electron geometry is determined by all electron pairs, whereas the molecular geometry considers only the positions of the atoms, leading to a difference.
The molecular geometry of chloroform (CHCl3) is tetrahedral. This means that the central carbon atom is surrounded by three hydrogen atoms and one chlorine atom, with the bond angles between these atoms being approximately 109.5 degrees.
