Determining molecular geometry and bond angles
| Attachments | Molecular Geometry | Bond Angles |
|---|---|---|
| 2 | linear | 180 |
| 3 | trigonal planar | 120 |

What are the 5 basic molecular geometries?
The 6 basic molecular shapes are linear, trigonal planar, angular (bent), tetrahedral, trigonal pyramidal, and trigonal bipyramidal.
What is the bond angle of a trigonal pyramidal?
For trigonal pyramidal geometry the bond angle is slightly less than 109.5 degrees, around 107 degrees. For bent molecular geometry when the electron-pair geometry is tetrahedral the bond angle is around 105 degrees.
How do you find the number of bond angles?
- Write the Lewis dot structure for the molecule. Assume that you must determine the bond angles in BF3.
- Use The steric number and VSEPR theory to determine the electron domain geometry of the molecule.
- Use the VSEPR shape to determine the angles between three electron domains.

How many angles are there in the tetrahedral structure?
In a tetrahedral molecular geometry, a central atom is located at the center with four substituents that are located at the corners of a tetrahedron. The bond angles are cos−1(−1⁄3) = 109.4712206……
| Tetrahedral molecular geometry | |

What are the bond angles for trigonal pyramidal?
What are the angles in a trigonal planar geometry?
In a trigonal planar compound has a central atom attached to three atoms arranged in a triangular shape around the central atom. All four atoms lie flat on a plane. In an ideal trigonal planar species, all three ligands are identical and all bond angles are 120°.
