Unit 6 Practice Test Covalent Bonding & VSEPR

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed when two atoms share one or more pairs of electrons.

Front

What is the 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 is the Lewis structure?

Back

A Lewis structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

What is hybridization?

Back

Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals suitable for the pairing of electrons to form chemical bonds.

Front

What is sp hybridization?

Back

sp hybridization occurs when one s orbital and one p orbital mix to form two equivalent sp hybrid orbitals, typically resulting in a linear geometry.

Front

What is sp² hybridization?

Back

sp² hybridization occurs when one s orbital and two p orbitals mix to form three equivalent sp² hybrid orbitals, typically resulting in a trigonal planar geometry.

Front

What is sp³ hybridization?

Back

sp³ hybridization occurs when one s orbital and three p orbitals mix to form four equivalent sp³ hybrid orbitals, typically resulting in a tetrahedral geometry.

Front

What are polar molecules?

Back

Polar molecules are molecules that have a net dipole moment due to the presence of polar bonds and an asymmetrical shape.

Front

What are nonpolar molecules?

Back

Nonpolar molecules are molecules that do not have a net dipole moment, often due to symmetrical shapes or equal sharing of electrons.

Front

What are intermolecular forces?

Back

Intermolecular forces are forces of attraction or repulsion between neighboring particles (atoms, molecules, or ions).
