Valence covering Electron Pair Repulsion (VSEPR) Theory
oIn Valance covering Electron Pair Repulsion (VSPER) theory, the electrons the surround the central atom the molecule space arranged in together a way that they minimize the electron-electron repulsions.
oThis plan of electrons deserve to be provided to suspect the geometrical shape of polyatomic molecules by calculating the bond pair and lone pair of electrons neighboring the main atom/ions.
The molecular form of miscellaneous molecules having specific number of lone pair of electrons and bonding pair of electrons are offered below:
Number of bonding teams on main atom | Number that lone pairs on main atom | Molecular notation | Electron-pair geometry | Molecular geometry |
2 | 0 | linear | Linear | |
3 | 0 | trigonal planar | trigonal planar | |
2 | 1 | trigonal planar | bent | |
4 | 0 | tetrahedral | tetrahedral | |
5 | 0 | trigonal bipyramidal | trigonal bipyramidal | |
3 | 2 | trigonal bipyramidal | T-shape | |
4 | 1 | trigonal bipyramidal | seesaw | |
4 | 2 | octahedral | square planar |
The geometrical shape of molecules which deserve to be figured out by calculating the number of bond pair and also lone pair that electrons and also steps associated in the calculation is given below:
Step.1: compose the electron dot formula from the provided molecular formula.
Step.2: identify the total number of bonding pair electrons and lone pair the electrons that present about the main atom.
Step.3: identify the setup of this electron pairs roughly the main atom to find the electron geometry.
(b)
The electron dot framework of
is provided below:The total number of bond pair of electron = 2.
The total variety of lone pair of electrons = 2.
Therefore, the electron geometry of molecule is “tetrahedral.”
(c)
The electron dot framework of
is provided below:The total variety of bond pair of electron = 3.
The total number of lone pair of electrons = 2.
Therefore, the electron geometry the molecule is “trigonal bipyramidal.”
(d)
The electron dot framework of
is given below:The total variety of bond pair of electron = 3.
The total variety of lone pair of electrons = 0.
Therefore, the electron geometry that molecule is “trigonal planar.”
