∙ 9y agoThe presence of a lone pair reduces the bond angle between the bonding pair of electrons. Most compounds containing a lone pair of electrons are not symmetric in structure.

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 A pair of electrons not involved in bonding called?
Such pairs of electrons are called as lone pairs.
Why is CH4 molecular shape tetrahedral?
It has no lone pairs.It has four even repulsive units
How does a lone pair contribute a molecular shape?
It takes up space like an "invisible" atom.
Why do water molecules have bent shape and carbon dioxide molecules have a linear shape?
In a water molecule, there are two lone pairs of electrons connected to the oxygen. The lone pairs push the hydrogen atoms, creating a bent shape. In CO2, however, there are two double bonds and no lone electrons on the central atom, hence the molecule has a linear shape.
What effect does a lone electron pair have on molecular shape?
The lone pair pushes bonding electron pairs away.
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 effect does a lone electron have on a molecular shape?
The lone pair pushes bonding electron pairs away.
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 effect does a lone electron pair on molecular shape?
The lone pair pushes bonding electron pairs away.
What effect does a lone electron pair have a molecular shape?
The lone pair pushes bonding electron pairs away.
What is molecular shape of BF3?
The shape of this molecule is Trigonal Planar. this is because it has no lone pairs of electrons so it maintains a 2D shape.
Which molecular shape has two lone pairs and two bonding pairs of electrons around the central atom?
linear
What is the molecular geometry of a methane (CH4) molecule?
Methane has a tetrahedral molecular geometry. It has 4 bonding pairs of electrons and no lone pairs.
How does lone pairs 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.

What is the molecular shape of HC2?
H2S has two lone pairs.They make it a bent.
