Honors Chem Molecular Geometry with VSEPR & MOT

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 the electron pairs in the valence shell of the central atom.

Front

What is the bond angle in a tetrahedral molecule?

Back

The bond angle in a tetrahedral molecule is approximately 109.5 degrees.

Front

What is the molecular shape of CH4 (methane)?

Back

The molecular shape of CH4 is tetrahedral.

Front

What is the molecular shape of H2O (water)?

Back

The molecular shape of H2O is bent or angular due to the two lone pairs on the oxygen atom.

Front

What is the bond angle in a trigonal planar molecule?

Back

The bond angle in a trigonal planar molecule is approximately 120 degrees.

Front

What is the molecular shape of BF3 (boron trifluoride)?

Back

The molecular shape of BF3 is trigonal planar.

Front

What is the molecular shape of NH3 (ammonia)?

Back

The molecular shape of NH3 is trigonal pyramidal due to the presence of one lone pair on the nitrogen atom.

Front

What is the bond angle in a linear molecule?

Back

The bond angle in a linear molecule is 180 degrees.

Front

What is the significance of lone pairs in molecular geometry?

Back

Lone pairs occupy space and can affect the bond angles and overall shape of the molecule.

Front

What is the molecular shape of CO2 (carbon dioxide)?

Back

The molecular shape of CO2 is linear.
