Can you determine molecular geometry from a Lewis structure?
The Lewis structure helps us identify the bond pairs and the lone pairs. Then, with the Lewis structure, we apply the valence-shell electron-pair repulsion (VSPER) theory to determine the molecular geometry and the electron-group geometry.
What type of bond is AsF5?
Vapor density measurements indicate some degree of association, but it is a monomeric covalent compound with a high degree of coordinating ability. It is prepared by reacting fluorine with arsenic metal or arsenic trifluoride.
What is the molecular geometry of clf3?
The electron geometry of chlorine trifluoride is trigonal bipyramidal with a 175° F-Cl-F bond angle.
How do you find the molecular geometry of a molecule?
- VSEPR Rules:
- Identify the central atom.
- Count its valence electrons.
- Add one electron for each bonding atom.
- Add or subtract electrons for charge (see Top Tip)
- Divide the total of these by 2 to find the total.
- number of electron pairs.
- Use this number to predict the shape.
What factors determine the molecular geometry?
Many factors lead to variations from the ideal bond angles of a molecular shape. Size of the atoms involved, presence of lone pairs, multiple bonds, large groups attached to the central atom, and the environment that the molecule is found in are all common factors to take into consideration.
Is tef5 polar or nonpolar?
This ion is considered to be polar.
What is AsF5 used for?
Arsenic Pentafluoride is a colorless gas that forms white fumes in air. It is used in making electroconductive polymers.
What is the name of AsF5?

Can AsF5 be formed?
Synthesis. Arsenic pentafluoride can be prepared by direct combination of arsenic and fluorine: 2As + 5F2 → 2AsF.
