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

Electrons will try to move as far apart as possible to minimize repulsion.

Front

What molecular shape does H2O have?

Back

Bent.

Front

Define a lone pair in the context of molecular geometry.

Back

A pair of non-bonding electrons.

Front

What is the molecular geometry of BF3?

Back

Trigonal planar.

Front

What molecular geometry does PH3 exhibit?

Back

Trigonal pyramidal.

Front

How does the presence of lone pairs affect molecular geometry?

Back

Lone pairs occupy space and can alter bond angles, leading to different shapes.

Front

What is the bond angle in a tetrahedral molecular geometry?

Back

Approximately 109.5 degrees.

Front

What is the molecular shape of CO2?

Back

Linear.

Front

What is the difference between bonding pairs and lone pairs?

Back

Bonding pairs are involved in chemical bonds, while lone pairs are not involved in bonding.
