Why py and pz cannot form bonding and anti bonding molecular orbital?
Bluemarmaide
Standard PY and PZ cannot form bonding and anti bonding molecular oribitals due to their structural differences. Depending on the composition of the bonds, most atoms and molecules can create orbitals.

What is the difference between bonding and anti bonding molecular orbital?
Bonding molecular orbitals result from constructive interference of atomic orbitals, leading to increased electron density between nuclei and a lower energy state. Anti-bonding molecular orbitals result from destructive interference and have a node between nuclei, which weakens the bond and raises the energy of the molecular system.
Difference between bonding and anti bonding molecular orbital?
In bonding molecular orbitals, the electron density between two atoms helps stabilize the molecule. In anti-bonding molecular orbitals, there is a node between the nuclei where there is no electron density, leading to destabilization of the molecule.
Is oxygen paramagnetic?
Oxygen, O2 is paramagnetic indicating 2 unpaired electrons, howver simple bonding schemes for O2 with its 12 electrons would predict that they would all be paired. A molecular orbital treatment of O2 shows that there are two degenerate (equal energy) anti-bonding pi orbitals that each holds one electron.
Why do anti bonding molecular orbitals are formed?
Anti-bonding molecular orbitals are formed due to destructive interference between atomic orbitals when they combine. This leads to a region of electron density with higher energy than the separate atomic orbitals, resulting in weak or no bonding. The presence of anti-bonding orbitals can destabilize a molecule and weaken its overall bond strength.
Why Be2 does not exist according to mo theory?
In molecular orbital (MO) theory, the Be2 molecule does not exist because it would require the combination of two beryllium atoms, both of which have only two valence electrons. When these atoms come together, there are not enough valence electrons available to form stable bonding molecular orbitals due to the absence of unpaired electrons for bonding. This results in an energetically unfavorable situation, leading to Be2 being unstable and non-existent.
What is the difference between bonding and anti bonding molecular orbital?

What are the postulates of molecular orbit theory?
Molecular Orbital Theory (MOT):•Basic idea of MOT is that atomic orbitals of individual atoms combine toform molecular orbitals. Electrons in molecule are present in themolecular orbitals which are associated with several nuclei.•The molecular orbital formed by the addition of atomic orbitals is calledthe bonding molecular orbital (s ).•The molecular orbital formed by the subtraction of atomic orbital is calledanti-bonding molecular orbital (s*).•The sigma (s ) molecular orbitals are symmetrical around the bond-axiswhile pi (p ) molecular orbitals are not symmetrical.•Sequence of energy levels of molecular orbitals changes for diatomicmolecules like Li2, Be2, B2, C2, N2 is 1s < *1s < 2s< *2s < ( 2px = 2py)

What species have no electrons in anti bonding 2p molecular orbitals?
f2
What are pi acceptor ligand?
Pi acceptor ligands are ligands that can accept electron density from a metal center via their pi orbitals. These ligands typically have pi bonding interactions with the metal, allowing for back-donation of electron density from the metal to the ligand. Pi acceptor ligands are often strong-field ligands that influence the electronic structure and reactivity of metal complexes.
Which chemical bond most likely stores the most energy?
C=c Double carbon-carbon bond
What is the bonding order of hydrogen iodide?
HI has a bond order of 1. H 1s1 + I 5p5 gives one filled (2 electrons) sigma bonding oribital and one empty anti-bonding orbital. bond order= 1/2 (bonding electrons-anti-bonding electrons) = 1/2(2-0) = 1
SiF4 bond type?
:Structure of SiF4 is a regular tetrahedron, any regular geometry has net zero dipole moment as all individual dipole in a molecule cancel the effect of each other. About paramagnetic behaviour of oxygen gas, according to the Molecular Orbital theory oxygen has two unpaired electron in its Pi anti bonding molecular orbital, which is the cause of their paramagnetism.
Why nitrogen is diamagnetic while contains unpaired electrons?
If you are going by the electron configuration of nitrogen then the unpaired electrons in the 2p shell would indicate that it is paramagnetic. However experiments show that it is diamagnetic. You must remember that nitrogen is a diatomic element and as such is found as N2. The molecular orbital theory explains how there are no unpaired electrons in the bonds between the two N atoms. The 1s and 2s molecular orbitals are completely filled and all of the bonding 2p orbitals are also filled. There are no electrons in the any of the 2p anti-bonding orbitals. Seeing a molecular orbital diagram for N2 will clarify what i mean.
Is oxygen paramagnetic?

A molecular orbital treatment of O2 shows that there are two degenerate (equal energy) anti-bonding pi orbitals that each holds one electron.
Why carbon can not form fourth covalent bond?
With itself. Molecular bonding theory and the bond order show a sigma pi discrepancy ( bonding/anti-bonding ) that disallows this tetra-covalent carbon to carbon interaction. Google this for a fuller explanation.
What is back bonding in metal carbonyls?
Back bonding in metal carbonyls refers to a type of bonding interaction where electrons from the carbonyl group (CO) donate into empty d-orbitals of the metal atom. This results in the sharing of electron density between the metal and the carbonyl ligand, leading to enhanced stability of the complex. Back bonding is a key feature of metal carbonyl complexes and plays a significant role in their reactivity and bonding properties.
