Lone pairs influence molecular shape by repelling bonding pairs of electrons, which alters the arrangement of atoms in a molecule. According to VSEPR (Valence Shell Electron Pair Repulsion) theory, lone pairs occupy more space than bonding pairs, leading to distortions in the geometry. This results in shapes such as bent or pyramidal, as seen in molecules like water (H₂O) and ammonia (NH₃), where the presence of lone pairs affects bond angles and overall molecular geometry.

What effect does a lone electron pair have a molecular shape?
The lone pair pushes bonding electron pairs away.
If a molecule has the general formula AX5 but has octahedral molecular geometry what is its molecular shape?
A molecule with the general formula AX5 suggests that it has five bonding pairs of electrons and one lone pair of electrons. In an octahedral arrangement, the presence of one lone pair distorts the geometry, resulting in a square pyramidal molecular shape. Therefore, the molecular shape of AX5 with octahedral geometry is square pyramidal.

What is the molecular shape of HClO?
It is a bent molecule because of Oxygen's lone pairs
How does a lone pair contribute to a molecular shape?

How does a lone pair contribute to the molecular shape?
A lone pair of electrons can affect the molecular shape by repelling bonded pairs of electrons, causing distortions in the molecule's geometry. This can lead to changes in bond angles and overall molecular shape.

What effect does a lone electron pair have a molecular shape?
The lone pair pushes bonding electron pairs away.
What effect does a lone electron pair on 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.
Molecular shape of PH3?
PH3 has 3 bonding pairs and 1 non-bonding pair of electrons. Its electron pair geometry is Tetrahedral and its molecular geometry is Trigonal Pyramidal.
What is the molecular shape of MH3?
The molecular shape of MH3 is trigonal pyramidal. This shape occurs when a central atom (M) is bonded to three other atoms (H) and has one lone pair of electrons.
