How does the lone pair contribute to molecule shape?
It takes up space like an "invisible" atom.
How does a lone pair disort the molecular shape?
The lone pair forces bonding atoms away from itself
What effect does a lone electron pair have a molecular shape?
The lone pair pushes bonding electron pairs away.
Bond angle of NH3?
107.5 approximately, as the molecule is based on a tetrahedral shape, which should have 109.5 degree bonds, but the lone pair on the N causes the bond angles to be slightly decreased, by about 2 degrees
What is the molecular shape of NClO2?
An NCl3 molecule would be a trigonal pyramidal because it has one center N atom with 3 Cl surrounding it, but also a lone pair of electrons on the top which bends the molecule downward, forming a trigonal pyramidal. Its electron shape would be tetrahedral, that is when you count the lone pairs of electrons as bonds themselves.
How does a lone pair distort the molecualr shape?
The lone pair creates repulsion between the molecules attached to it and distorts the shape.
Why does the presence of lone pairs contribute to the polarity of a water molecule?
How do lone pairs around the central atom affect the polarity of the molecule?
How you get bond angle of a tetrahedral shape molecule which have 1 lone pair?
Tetrahedral bond angle of a molecule which have a lone pair electron is 107, smaller than regular 109.5, due to the repulsion of electrons of lone pair.
How does a lone pair contribute to the molecular shape?
Lone pairs do not affect the shape of diatomic molecules, and Lone pairs are electrons that are not in bonds. Lone pairs do not affect the shape if they are not on the central atom.
What is the shape of the molecule of nbr3?
The lone unbonded pair of electrons around nitrogen dictates that the NBr3 molecule will have a 3-D trigonal pyramidal shape.
How does the lone pair contribute to molecule shape?
It takes up space like an "invisible" atom.
How does a lone pair distort the molecular shape?
A lone pair of electrons takes up space despite being very small. Lone pairs have a greater repulsive effect than bonding pairs. This is because there are already other forces needing to be taken into consideration with bond pairs. So to summarize: Lone pair-lone pair repulsion > lone pair-bond pair repulsion > bond pair-bond pair repulsion. This makes the molecular geometry different.
In XeO3 Xe show sp3 but shape is pyramidal why?
in XeO3 ,Xe shows sp3 but shape is pyramidal because of the presence of a lone pair of electrons on the central xenon atom. This lone pair distorts the shape of the molecule making it pyramidal.

How does the lone pair contributes to molecular shape?
The lone pair repels the electrons of the adjacent bonds more so than does a bonding pair of electrons, so thus alters the molecular geometry of the molecule.

What is the function of the lone pair electrons in the molecules?
In terms of struture, lone pairs contribute helping a molecule acquire a shape as dictated by VSEPR Theory (Valence Shell Electron Pair Repulsion Theory). Regarding chemical properties lone pair/s of electrons can make a molecule act as a Lewis base (like ammonia) in the reaction mixtures the extent of which depends on various other features in the structure of molecule.
