Capitolo 9, Problema 74c
Indicate whether each statement is true or false. (c) Molecules containing electrons that occupy antibonding orbitals must be unstable.
Guida verificata passo dopo passo1
Understand the concept of molecular orbitals: In molecular orbital theory, electrons are distributed in bonding and antibonding orbitals. Bonding orbitals stabilize the molecule, while antibonding orbitals can destabilize it.
Consider the role of antibonding orbitals: Electrons in antibonding orbitals can reduce the overall bond order, which is calculated as (number of electrons in bonding orbitals - number of electrons in antibonding orbitals) / 2.
Evaluate the stability of a molecule: A molecule is considered stable if it has a positive bond order, meaning there are more electrons in bonding orbitals than in antibonding orbitals.
Analyze the statement: The presence of electrons in antibonding orbitals does not necessarily make a molecule unstable. It depends on the overall bond order. If the bond order is positive, the molecule can still be stable despite having electrons in antibonding orbitals.
Conclude the analysis: Therefore, the statement 'Molecules containing electrons that occupy antibonding orbitals must be unstable' is false, as stability depends on the net effect of both bonding and antibonding electrons.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
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 Orbital Theory
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.
