Indicate whether each statement is true or false. (c) Molecules containing electrons that occupy antibonding orbitals must be unstable.

Key Concepts

Antibonding Orbitals

Antibonding orbitals are molecular orbitals that result from the destructive interference of atomic orbitals. When electrons occupy these orbitals, they tend to destabilize the molecule because they are associated with higher energy levels and can weaken the bond between atoms. This is in contrast to bonding orbitals, which stabilize the molecule by promoting electron sharing.

Molecular Stability

Molecular stability refers to the tendency of a molecule to maintain its structure and resist decomposition. A stable molecule typically has a favorable balance of bonding and antibonding electrons, with more electrons in bonding orbitals than in antibonding ones. When a molecule has a significant number of electrons in antibonding orbitals, it is generally less stable and more likely to break apart.

True/False Statements in Chemistry

In chemistry, true/false statements often require an understanding of underlying principles and definitions. Evaluating such statements involves analyzing the accuracy of claims based on established scientific knowledge. For example, determining whether a molecule with electrons in antibonding orbitals is unstable requires knowledge of molecular orbital theory and the implications of electron distribution on stability.
