VSEPR Flashcard

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion.

Front

What is the main principle of VSEPR theory?

Back

The shape of a molecule is determined by the repulsion between electron pairs around the central atom.

Front

What is the molecular shape of a molecule with 2 bonding pairs and 1 lone pair?

Back

Bent.

Front

What is the molecular geometry of a molecule with 4 bonding pairs and no lone pairs?

Back

Tetrahedral.

Front

What type of bond occurs when electrons are shared unequally between atoms?

Back

Polar covalent bond.

Front

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

Back

Trigonal pyramidal.

Front

How do lone pairs affect molecular geometry?

Back

Lone pairs take up more space than bonding pairs, affecting the overall shape.

Front

What is the geometry of a molecule with 5 bonding pairs and no lone pairs?

Back

Trigonal bipyramidal.

Front

What is the bond angle in a tetrahedral molecule?

Back

Approximately 109.5 degrees.

Front

What is the bond angle in a trigonal planar molecule?

Back

Approximately 120 degrees.
