Chemical Bonds Test #2: Concepts 4-6

Front

What is the molecular shape for an element with 3 electron domains?

Back

Trigonal planar.

Front

What does VSEPR theory state about electron pairs?

Back

It is the tendency for electron pairs to want to be as far apart as possible because valence electrons are repulsed by each other.

Front

Which of the following is NOT considered an electron domain?

Back

Central atom.

Front

What is the name of SF6?

Back

Sulfur hexafluoride.

Front

How does viscosity relate to intermolecular forces?

Back

The stronger the intermolecular forces, the higher the viscosity.

Front

Define electron domain.

Back

An electron domain is a region around a central atom where electrons are likely to be found, including lone pairs and bonds.

Front

What is the significance of lone pairs in molecular geometry?

Back

Lone pairs occupy space and can affect the shape of the molecule by repelling bonding pairs.

Front

What is the molecular shape of a molecule with 4 electron domains?

Back

Tetrahedral.

Front

How do double bonds count in VSEPR theory?

Back

Double bonds count as one electron domain.

Front

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

Back

Bent.
