VSEPR

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion

Front

What is the basic 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.

What is the electron geometry of CH₄?

Back

Tetrahedral

Front

How many lone pairs are present in a molecule with a trigonal planar geometry?

Back

0 lone pairs.

Front

What is the bond angle in a tetrahedral molecule?

Back

109.5^o

Front

What is the bond angle for a bent molecule with one lone pair?

Back

Approximately 120^o.

Front

What is the bond angle for a bent molecule with two lone pairs?

Back

104.5^o.

Front

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

Back

Tetrahedral

Front

What is the difference between electron geometry and molecular geometry?

Back

Electron geometry considers all electron pairs (bonding and lone), while molecular geometry considers only the arrangement of bonding pairs.
