What is the role of unshared electron pairs in predicting molecular geometries?
Lone electron pairs give the geometry a triangular base.
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 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.
What is the molecular geometry for BrF4?
When you do the VSEPR you get 6pairs of electron pairs and two lone pairs which means that when you look at the geometrical shape (by looking at how many pairs of electrons you got and in this cases its 6) the shape is octahedral but the molecular shape is square planar because you only have four atoms bonding and two lone pairs which means that the lone pairs have to be as far from each other as possible so they go on the two ends ( one on top and one on the bottom) which leavs the shape to be a square planar! i hope this helps you good luck. --------- TL;DR: Square Planar.
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.
What effect does a lone electron have on a molecular shape?
The lone pair pushes bonding electron pairs away.

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 does a lone electron pair have on molecular shape?
The lone pair pushes bonding electron pairs away.
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 HC2?
H2S has two lone pairs.They make it a bent.
What is the molecular shape of a molecular that has two electron pairs in which both pairs are shared?
linear
How does molecular shape effect polarity?
The molecular geometry of a compound helps to determine polarity because, it indicates the number of lone pairs on a central atom thus giving it specified angles and polarity (only if there are lone pairs because if there are no lone pairs on the central atom, them it is non-polar).
What is the molecular geometry of ICl5?
The molecular shape is square pyramidal because it has five ligands and one lone pair and the bond angle are 90,<120. Also, it has no dipole moment and the electron group geometry is octahedral.
What is the ammonia molecular shape?
The shape would be pyramidal because of the lone pair nitrogen has
What is H2's molecular shape?
Two lone pairs are found.So it is bent in shape.
