VSEPR Intro CW

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 electron pairs in the valence shell of the central atom.

Front

What determines the shape of a molecule according to VSEPR theory?

Back

The shape of a molecule is determined by the number of bonding pairs and lone pairs of electrons around the central atom.

Front

What is a domain in VSEPR theory?

Back

A domain refers to a region of electron density around a central atom, which can be a single bond, double bond, triple bond, or lone pair.

Front

How many domains does a molecule with 3 single bonds and 1 double bond have?

Back

4 domains.

Front

What is the electron geometry of a molecule with 4 domains?

Back

Tetrahedral.

Front

What is the molecular geometry of H2O?

Back

Bent.

Front

What is the shape of a molecule with 1 single bond and 1 triple bond?

Back

Linear.

Front

How many lone pairs does H2O have?

Back

2 lone pairs.

Front

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

Back

Trigonal pyramidal.

Front

What is the difference between electron geometry and molecular geometry?

Back

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