Valence Covering Electron Pair Repulsion (VSEPR) Theory
oIn Valance Covering Electron Pair Repulsion (VSPER) concept, the electrons that surround the central atom of molecule are arranged in such a means that they minimize the electron-electron repulsions.
oThis plan of electrons have the right to be used to predict the geometrical shape of polyatomic molecules by calculating the bond pair and lone pair of electrons bordering the central atom/ions.
The molecular form of miscellaneous molecules having actually particular variety of lone pair of electrons and also bonding pair of electrons are offered below:
Number of bonding teams on main atom | Number of 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 can be figured out by calculating the variety of bond pair and also lone pair of electrons and procedures involved in the calculation is offered below:
Step.1: Write the electron dot formula from the given molecular formula.
Step.2: Determine the full variety of bonding pair electrons and lone pair of electrons that existing approximately the central atom.
Step.3: Determine the plan of these electron pairs roughly the main atom to uncover the electron geomeattempt.
(b)
The electron dot structure of
is offered below:The total number of bond pair of electrons = 2.
The full number of lone pair of electrons = 2.
Therefore, the electron geometry of molecule is “tetrahedral.”
(c)
The electron dot structure of
is offered below:The complete variety of bond pair of electrons = 3.
The full number of lone pair of electrons = 2.
Therefore, the electron geomeattempt of molecule is “trigonal bipyramidal.”
(d)
The electron dot framework of
is provided below:The full number of bond pair of electrons = 3.
The full variety of lone pair of electrons = 0.
Thus, the electron geomeattempt of molecule is “trigonal planar.”
Ans: Part bThe electron geomeattempt of

is given below: Part dThe electron geometry of
is offered below:00
