molecular theory explains weather a molecule will exist or not on the basis of bond order. that is by taking difference of bonding and antibonding electrons.this seems good for diatomic molecule but fails for polyatomic molecule. for example, take He3 molecule. according to molecular orbital theory the bond order comes out to be one which implies that the molecule must exist and must have a single bond in it. but no such molecule exist practically.

What is the role of a node in the molecular orbital theory of chemistry?
In molecular orbital theory, a node is a point in a molecular orbital where the probability of finding an electron is zero. Nodes help determine the shape and energy of the molecular orbital, influencing the chemical properties of the molecule.
What is the significance of the "no mo diagram" in the context of molecular orbital theory?
The "no mo diagram" is significant in molecular orbital theory because it helps visualize the absence of molecular orbitals in certain molecular configurations. This diagram is used to show that when combining certain atomic orbitals, no new molecular orbitals are formed, indicating that the resulting molecule does not have any unique bonding or anti-bonding interactions.
What is the significance of the n2 MO diagram in molecular orbital theory?
The n2 MO diagram in molecular orbital theory is significant because it helps to explain the bonding and electronic structure of molecules. It shows how atomic orbitals combine to form molecular orbitals, which determine the stability and properties of the molecule. This diagram is crucial for understanding the behavior of electrons in chemical reactions and predicting the reactivity of molecules.
What is the difference between the homo and lumo energy levels in molecular orbital theory?
In molecular orbital theory, the HOMO (highest occupied molecular orbital) is the highest energy level that contains electrons, while the LUMO (lowest unoccupied molecular orbital) is the lowest energy level that does not contain electrons. The difference between the HOMO and LUMO energy levels determines the reactivity and stability of a molecule.
What is the significance of the molecular orbital theory in chemistry, and how can it be understood without the use of a molecular orbital diagram?
The molecular orbital theory in chemistry is significant because it helps explain the behavior and properties of molecules based on the interactions of their atomic orbitals. It allows us to predict the stability and reactivity of molecules. One way to understand molecular orbital theory without using a diagram is to think of it as a way to combine the atomic orbitals of individual atoms to form new molecular orbitals. These new orbitals can be bonding, anti-bonding, or non-bonding, which determine the overall stability and properties of the molecule. By considering the overlap of atomic orbitals and the resulting interactions, we can understand how molecules form and behave without needing a visual representation.

Can orbital hybridization theory can describe both the shape and bonding of the molecules?
Orbital hybridization provides information about both molecular bonding and molecular shape.

What is the disadvantages of molecular orbital approach?
Some disadvantages of the molecular orbital approach include the complexity of calculations involved, especially for larger molecules, as well as difficulties in accurately predicting electronic interactions in systems with strong electron correlation. Additionally, the interpretation of molecular orbital diagrams can sometimes be challenging for non-experts due to the abstract nature of the theory.
Molecular orbital theory is based upon which model of the atom?
Molecular orbital theory determines molecular structure that the electrons are not assigned as individual bonds between atoms, however, are treated as moving under the influence of the nuclei in the whole molecule.
What theory provides information concerning both molecular shape and molecular bonding?
The VSEPR (Valence Shell Electron Pair Repulsion) theory provides information about both molecular shape and molecular bonding. It helps predict the geometric shapes of molecules based on the arrangement of electron pairs around the central atom and takes into account the repulsion between electron pairs to determine the overall molecular shape.
What are the key differences between valence bond theory and molecular orbital theory in explaining chemical bonding?
Valence bond theory focuses on the overlap of atomic orbitals to form bonds between atoms, emphasizing the localized nature of bonding. Molecular orbital theory considers the entire molecule as a whole, with electrons delocalized over the entire molecule, leading to the formation of molecular orbitals.
What is low line sigma m orbital?
A low-lying sigma molecular orbital is a symmetrical orbital formed by the overlap of atomic orbitals in a molecule. It typically has a relatively low energy level compared to other molecular orbitals, and it plays a key role in bonding between atoms in a molecule. The "m" designation in this context may refer to a molecular orbital belonging to a specific symmetry group in molecular orbital theory.
