Interpretation:
The similarities and the differences between VB theory and MO theory are to be stated.
Concept introduction:
When two atomic orbitals come close to each other they lose their identity and form new pair of orbitals knows as molecular orbitals. Among the two molecular orbitals formed, one has energy lower than the atomic orbitals is known as bonding molecular orbital and the other has energy higher than the atomic orbitals and is known as antibonding molecular orbital. The electrons in molecular orbitals are filled according to Aufbau’s principle and Hund’s rule.

- Construct the symmetry-adapted linear combination molecular orbitals for hydrogen sulfide, H2S.arrow_forwardUse molecular orbital arguments to decide whether or not the difluoride dianion, F22, should exist as a stable ion.arrow_forwardPredict the valence electron configuration and the totalbond order for the molecule I2. Will I2 be paramagnetic or diamagnetic?arrow_forward
- Can you just explain this more in-depth? I don’t understand why the lone pair is in a p orbital at the top but not at the bottom? Maybe I need to brush up on MO theory but I don’t get what the criteria is to determine that.arrow_forwardConsider the ClO4 – anion. Use symmetry analysis to determine the orbitals used in bonding by the central atom. (a) As a consequence of the multiple Cn axes with n > 2, the pi bonding cannot be separated into perpendicular and parallel components as was done with SO3. Rather these orbitals must be operated on together, an inseparable pair.arrow_forwardSet up the secular determinants for (i) linear H4, (ii) cyclic H4 within the Hückel approximation.arrow_forward
- Consider the C2v molecule OF2; take the molecule to lie in the yz-plane, with z directed along the C2 axis; the mirror plane σ′v is the yz-plane, and σv is the xz-plane. The combination pz(A) + pz(B) of the two F atoms spans A1, and the combination pz(A) − pz(B) of the two F atoms spans B2. Are there any valence orbitals of the central O atom that can have a non-zero overlap with these combinations of F orbitals? How would the situation be different in SF2, where 3d orbitals might be available?arrow_forward(a) Use the simple one-electron molecular orbital method, including overlap, to calculate the energies of the molecular orbitals of the hydrogen molecule (H2) in terms of α, β and S?arrow_forwardhow is molecular orbital (MO) theory an improvement over lewis structures. lewis structures are simpe to learn to draw MO theory better handles the delocalization of electrons MO theory doesnt require any complex calculations MO theory allows us to directly solve schrodingers equation for a moleculearrow_forward
