VSEPR

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion

Front

What is the main principle of VSEPR theory?

Back

The shape of a molecule is determined by the repulsion between electron pairs in the valence shell of the central atom.

Front

How does a lone pair affect molecular geometry?

Back

A lone pair occupies more space than bonding pairs, which can distort the geometry of the molecule.

Front

What is the electron geometry for a molecule with 4 electron groups?

Back

Tetrahedral

Front

What is the molecular geometry of a molecule with 2 bonding pairs and 1 lone pair?

Back

Bent

Front

What is the molecular geometry of a molecule with 3 bonding pairs and no lone pairs?

Back

Trigonal planar

Front

How many degrees are in a tetrahedral bond angle?

Back

Approximately 109.5 degrees

Front

What is the molecular geometry of CO2?

Back

Linear

Front

What is the molecular geometry of NH3?

Back

Trigonal pyramidal

Front

What is the effect of multiple bonds on molecular geometry?

Back

Multiple bonds count as one electron group but can affect bond angles due to increased electron density.
