VSEPR and Molecular Geometry

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion

Front

What is the main principle of VSEPR theory?

Back

Molecular shapes are determined by the repulsion between electron pairs around a central atom.

Front

How many electron groups are around a central atom in a linear molecular geometry?

Back

2

Front

What is the molecular geometry of a molecule with 4 electron groups?

Back

Tetrahedral

Front

What is the molecular geometry of a molecule with 3 bonding pairs and 1 lone pair?

Back

Trigonal pyramidal

Front

What is the bond angle in a tetrahedral molecular geometry?

Back

Approximately 109.5 degrees

Front

Which molecule has a bent shape due to lone pairs?

Back

H₂O (Water)

Front

What is the molecular geometry of CO₂?

Back

Linear

Front

How does the presence of lone pairs affect molecular geometry?

Back

Lone pairs repel more strongly than bonding pairs, altering bond angles.
