When the electron pair and molecular geometry are different?
Electron pair geometry considers both bonding and lone pairs of electrons around a central atom, while molecular geometry focuses solely on the arrangement of bonded atoms. This can lead to different geometries when there are lone pairs present; for example, in ammonia (NH₃), the electron pair geometry is tetrahedral due to one lone pair, but the molecular geometry is trigonal pyramidal. The presence of lone pairs affects bond angles and the overall shape of the molecule, resulting in distinct geometries.
What is the role of unshared electron pairs in predicting molecular geometries?
Lone electron pairs give the geometry a triangular base.
What is the electron geometry and molecular geometry of SBr2?
The electron geometry of SBr2 (sulfur dibromide) is tetrahedral due to the presence of four regions of electron density around the sulfur atom: two bonding pairs with bromine atoms and two lone pairs. However, the molecular geometry, which considers only the arrangement of the atoms, is bent or V-shaped because the lone pairs repel the bonding pairs, altering the shape.
Which type of hybridization leads to a bent moelcular geometry and tetraheadral electron domain geometry?
The type of hybridization that leads to a bent molecular geometry with a tetrahedral electron domain geometry is sp³ hybridization. In this case, there are four electron domains around the central atom, but if two of those domains are lone pairs, the resulting molecular shape is bent. An example of this is water (H₂O), where the oxygen atom is sp³ hybridized, leading to a bent shape due to the repulsion between the two lone pairs.
If all of the electron groups around a central atom are bonding groups (that is there are no lone pairs) what is the molecular geometry for two electron groups?
linear
What effect does a lone electron have on a molecular shape?
The lone pair pushes bonding electron pairs away.

What is the molecular shape of HClO?
It is a bent molecule because of Oxygen's lone pairs
What effect does lone pair electrons have on molecular shape?
The lone pair pushes bonding electron pairs away.
What is the molecular geometry of NH2-?
NH2- is sp3 hybridized and there is 2 bonding and 2 lone pair of electron,that's why shape of NH2 is angular.

What is the molecular shape of iodine difluoride?
Iodine difluoride (IF2) has a linear molecular shape due to the presence of two bonding pairs and one lone pair on the iodine atom. This arrangement of electron pairs gives it a linear geometry.
What is the molecular shape of HC2?
The molecular shape of HC2 is linear. There are only two atoms in the molecule and no lone pairs of electrons, resulting in a linear geometry.
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 is the molecular shape of a molecular that has two electron pairs in which both pairs are shared?
linear
