Practice Problems Unit 4 Lesson 4

Front

What are bonding electrons?

Back

Bonding electrons are the electrons that are shared between atoms in a molecule, contributing to the formation of chemical bonds.

Front

What are antibonding electrons?

Back

Antibonding electrons are the electrons that occupy molecular orbitals that are higher in energy than the bonding orbitals, which can weaken or prevent bond formation.

Front

How do you determine the total number of bonding electrons in a molecule?

Back

Count the number of electrons in the bonding molecular orbitals from the molecular orbital diagram.

Front

How do you determine the total number of antibonding electrons in a molecule?

Back

Count the number of electrons in the antibonding molecular orbitals from the molecular orbital diagram.

Front

What is hybridization in chemistry?

Back

Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals that can accommodate the bonding of atoms.

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 seen in linear molecules.

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 seen in trigonal planar molecules.

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 seen in tetrahedral molecules.

Front

What is the significance of the Molecular Orbital Diagram?

Back

The Molecular Orbital Diagram visually represents the energy levels of molecular orbitals and helps predict the bond order, stability, and magnetic properties of a molecule.

Front

How do you calculate bond order from a Molecular Orbital Diagram?

Back

Bond order = (Number of bonding electrons - Number of antibonding electrons) / 2.
