Why antibonding orbital is higher in energy than bonding orbital?
antibonding molecular orbital have higher energy than bonding molecular orbital because in the word 'antibonding' there are more letters than in the word 'bonding'.. and hence antibonding molecular orbital has higher energy..
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 is a molecular orbital vs an atomic orbital?
according to MOT each energy level can be occupied by 2 electrons which must have opposite spins these pairs of electrons considered to occupy molecular orbital. so molecular orbital is formed from the overlap of the atomic orbitals of the atoms making up the bond.
How many electrons are in an antibonding orbital?
The first orbit only has an S orbital. The S orbital can hold 2 electron. The second orbit has s and p orbitals. The p orbital can hold 8 electrons The third orbit has s, p, and d orbitals. The d orbital hold 10 electrons giving a total of 18. However the 3d orbital has a higher energy level than 4s so the 4s orbital is filled with electrons before you can put electrons in the 3d orbital. The fourth orbital has s,p,d,and f. The f orbital can hold 14 electrons. This gives a total of 32 electrons. However the 4f orbital is higher in energy than the 5s, 5p, and 62 orbitals. Therefore these orbitals must be filled first. The fifth, sixth and seventh orbitals are similar to the fourth.
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.

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 happens when a diatomic molecule loses an electron Does the bond weaken?
No, it is not correct to say that the bond energy always decreases when a diatomic molecule loses an electron. F2 and O2 are counterexamples to this point. When a molecule loses an electron, it will come from the highest occupied molecular orbital. In both O2 and F2, this MO is an antibonding MO. Removing an electron from an antibonding MO *increases* the bond energy.
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.
Why will the He2 molecule will not form according to MOT?
The hypothetical He2 molecule would from from a formation of molecular orbitals from Helium's 1s orbitals. Whenever a molecular orbital is formed, there are two options, the constructive interference (bonding) MO, which has a lower energy than the atomic orbitals, and the destructive interference (antibonding) MO, which has a higher energy than the atomic orbitals. Since each He contributes two electrons to the molecule, there are enough electrons to fill both the bonding and antibonding MOs, giving an overall bond order of zero. This means the molecule does not hold together. Compare this to H2 where each atom only contributes one electron, filling only the bonding MO, giving a bond order of 1.
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 antibonding in chemistry?
Antibonding is a bonding in which the electrons are away from the nucleus and which is higher in energy.
Is there a posibility for a carbon to have 5 bonds?
No, if you take a look at the molecular orbitals of carbon, you will notice that its LUMO is the sigma antibonding orbital. This means if you try to put any electrons into a carbon with 4 existing bonds, you are actually breaking bonds. It can however, exist in an extremely unstable high energy intermediate.
