What species have no electrons in anti bonding 2p molecular orbitals?
f2
What is molecular orbitals extending over more that two atoms called?
Delocalised
Is a bonding orbital a molecular orbital whose energy is higher than that of the atomic orbitals from which it is formed?
no, it's a molecular orbit that can be occupied by two electrons of a covalent bond(:
What is hybridization orbital?
it gave me two answer and that is it
Is O2 2 paramagnetic?
No it is not paramagnetic.O2^2- has 2 electrons more than O2.Pi 2p molecular orbitals get completely filled hence it is diamagnetic.
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.
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)
How does a molecular orbital differ from an atomic orbital?
Molecular consists of multiple atomic orbitals
How is a molecular orbital formed?
In molecular orbital theory, MO theory, molecular orbitals are "built" from atomic orbitals. A common approach is to take a linear combination of atomic orbitals (LCAO), specifically symmetry adapted linear combinations (SALC) using group theory. The formation of a bond is essentially down to the overlap of the orbitals, the orbitals being of similar energy and the atomic orbital wave functions having the correct symmetry.
Indicate how bonding is explained in term of molecular orbitals?
When two atoms combine, the overlap of their atomic orbitals produces molecular orbitals. An atomic orbital belongs to a particular atom, whereas a molecular orbital belongs to a molecule as a whole. Much like an atomic orbital, two electrons are required to fill a molecular orbital. A bonding orbital is a molecular orbital occupied by the two electrons of a covalent bond
Are all sigma bonding molecular orbitals are gerade?
Yes ^^
What species have no electrons in anti bonding 2p molecular orbitals?
f2
Why are orbitals of the same energy level degenerate?
The reason that orbitals of the same energy level degeneracy is due to similar molecular structure. The orbitals contains electrons that cancel each other out.
Why carbon dioxide is a gas while silica is a solid?
First of all the molecular weight difference is enough to cause a major difference. Second, look at the electron orbitals of Silicon versus Carbon. Si containing molecules can do very different chemistry than just Carbon because of the orbitals that Si has available that carbon does not.
How atoms are combined to form molecule?
Through the sharing of electrons in molecular orbitals.
What is molecular orbitals extending over more that two atoms called?

Is the geometry of Allene planar according to the molecular orbitals applicable to its bonding?
of course!
