VSEPR and Molecular Geometry

Front

What is VSEPR theory?

Back

VSEPR (Valence Shell Electron Pair Repulsion) theory is a model used to predict the geometry of individual molecules based on the repulsion between electron pairs in the valence shell of the central atom.

What molecular shape does H2O have?

Back

H2O has a bent molecular shape due to the two lone pairs of electrons on the oxygen atom, which repel the hydrogen atoms.

Front

What is the molecular geometry of CO2?

Back

CO2 has a linear molecular geometry because it has two double bonds with oxygen atoms and no lone pairs on the central carbon atom.

Front

How many electron groups are around the central atom in a trigonal planar molecule?

Back

There are three electron groups around the central atom in a trigonal planar molecule.

Front

What is the molecular shape of BCl3?

Back

BCl3 has a trigonal planar molecular shape due to the three bonding pairs of electrons and no lone pairs on the boron atom.

Front

What determines the molecular geometry of a molecule?

Back

The molecular geometry is determined by the number of bonding pairs and lone pairs of electrons around the central atom.

Front

What is the shape of a molecule with four electron groups?

Back

A molecule with four electron groups typically has a tetrahedral shape.

Front

What is the difference between molecular geometry and electron geometry?

Back

Molecular geometry refers to the arrangement of atoms in a molecule, while electron geometry considers the spatial arrangement of all electron groups, including lone pairs.

Front

What molecular shape is associated with three bonding pairs and one lone pair?

Back

The molecular shape associated with three bonding pairs and one lone pair is trigonal pyramidal.

Front

Which molecule has a linear shape?

Back

CO2 (carbon dioxide) has a linear shape.
