The Molecular Geometry Calculator is a tool designed to determine the molecular structure of a compound based on the number of bonding pairs (B) and lone pairs (L) around the central atom. Understanding molecular geometry is crucial in various scientific fields, especially in chemistry, as it aids in predicting a molecule’s behavior, properties, and interactions with other substances.
Formula of Molecular Geometry Calculator
The following formulas are utilized by the Molecular Geometry Calculator to identify the molecular geometry based on the given bonding pairs and lone pairs:
- Linear: B = 2, L = 0
- Trigonal planar: B = 3, L = 0
- Bent (angular): B = 2, L = 1
- Tetrahedral: B = 4, L = 0
- Trigonal pyramidal: B = 3, L = 1
- Bent (angular): B = 2, L = 2
- Trigonal bipyramidal: B = 5, L = 0
- Seesaw: B = 4, L = 1
- T-shaped: B = 3, L = 2
- Linear: B = 2, L = 3
- Octahedral: B = 6, L = 0
- Square pyramidal: B = 5, L = 1
- Square planar: B = 4, L = 2
