- Double And Triple Bonds In Vsepr Theory
Molecular geometry is determined by possible locations of an electron in a valence shell, not by how many how many pairs of valence electrons are present. To see how the model works for a molecule with double bonds, consider...
- Vsepr Theory
Valence Shell Electron Pair Repulsion (VSPER) theory is used to predict the geometric shape of the molecules based on the electron repulsive force. There are some limitation to VSEPR.IntroductionThe shapes of the molecules is determined mainly by the...
- Formation Of H2o Molecule(bonds)
H2O molecule contains two Hydrogen atoms linked with a Oxygen atom. So we can describe the formation of Water molecule bond either by valence shell electron pair repultion theory or by Hybridization concept. ...
- Collision Theory
General Introduction:-Generally collision theory is the theory which explains about how chemical reaction takes place.The process of intermixing of reactants and striking between reacting species is called collision.The chemical reaction is only possible...
- Discovery Of Ions
The person who gives a theory of ions is Michael Faraday. It’s around 1830. He describes the portions of molecules that move from anode to cathode or vice versa. He discovered that certain substances when dissolved in water conduct an electric current....

Exceptions to VSEPR Theory
Valence Shell Electron Pair Repulsion theory does not always predict the correct geometry of molecules. Examples of exceptions include:
- transition metal molecules (e.g., CrO3 is trigonal bipyramidal, TiCl4 is tetrahedral)
- odd-electron molecules (CH3 is planar rather than trigonal pyramidal)
- some AX2E0 molecules (e.g., CaF2 has a bond angle of 145°)
- some AX2E2 molecules (e.g., Li2O is linear rather than bent)
- some AX6E1 molecules (e.g., XeF6 is octahedral rather than pentagonal pyramidal)
- some AX8E1 molecules
