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?
Electrons in a bonding orbital have lower energy levels than the average energy of a valence electrons in the isolated atoms between which the orbital is formed. Antibonding orbitals do not meet this criterion, so that anitbonding orbitals can be stable only in conjunction with bonding orbitals, whereas bonding orbitals can be formed without any accompanying antibonding orbitals.The molecular orbitals which is formed by the addition of atomic orbitals is called bonding molecular orbitals.The molecular orbitals which is formed by the subtraction of atomic orbitals is called antibonding molecular orbitals.
Difference between bonding and anti bonding molecular orbital?
Bonding molecular orbital Its energy is less than that of parent atomic orbital.It is more stable than the parent atomic orbital.In B.M.O, the probability of finding electrons is maximum.Contribution of B.M.O is maximum towards the shape of molecule.Anti-bondingmolecular orbital Its energy is greater than that of parent atomic orbital.It is less stable than the parent atomic orbital.In A.B.M.O, the probability of finding electrons is minimum.It does not contribute towards the shape of molecule.
What are pi acceptor ligand?
ligands which can accept electrons from the metal d orbital into there anti bonding orbital such as CO, or C=C
Which chemical bond most likely stores the most energy?
C=c Double carbon-carbon bond
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.

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 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

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?
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 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?
carbonyl in electron acceptor ligand it has empty orbital which can accept electron as well as filled orbital which can donate electrons . when carbonyl binds with metal it donates the electrons ,metal which is in low oxidation state now has excess electrons and it becomes stable if it back donate some electrons to the carbonyl in its anti bonding orbital forming a pi bond
