What is a ligand group orbitals?
What is a ligand group orbitals?
In molecular symmetry terms, the six lone-pair orbitals from the ligands (one from each ligand) form six symmetry adapted linear combinations (SALCs) of orbitals, also sometimes called ligand group orbitals (LGOs). The irreducible representations that these span are a1g, t1u and eg.
Is EDTA a strong field ligand?
en. CO.
Is EDTA a pi acceptor ligand?
EDTA, a hexadentate ligand, is an example of a polydentate ligand that has six donor atoms with electron pairs that can be used to bond to a central metal atom or ion.
How do you write a mo diagram?
FUNDAMENTAL STEPS IN DERIVING MO DIAGRAMS
- Find the valence electron configuration of each atom in the molecule.
- Decide if the molecule is homonuclear of heteronuclear.
- Fill molecular orbitals using energy and bonding properties of the overlapping atomic orbitals.
- Use the diagram to predict properties of the molecule.
What is SP sp2 sp3?
sp hybridization occurs due to the mixing of one s and one p atomic orbital, sp2 hybridization is the mixing of one s and two p atomic orbitals and sp3 hybridization is the mixing of one s and three p atomic orbitals.
Why is MO diagram of N2 and O2 different?
O2 and N2 have different number of electrons. Nitrogen has 7 electrons and they are distributed as: 2 in the first s orbit (1s2); 2 in the second s orbit (2s2); and three in the second p orbit (2p3). Oxygen has 8 electrons and they are distributed as: 1s2,2s2,2p4.
How to construct ligand group orbitals ( LGOs )?
Deriving Ligand Group Orbitals 1) Start with a complete set of equivalent atomic orbitals (i.e., a complete set of orbitals is one in which any given orbital is taken into another or some combination of other orbitals by a symmetry operation in the point group of interest – the 4 H(1s) orbitals in CH4 constitute a complete set) 2) Determine the
What are orbital diagrams?
Orbital diagrams are a visual way to show where the electrons are located within an atom.
How is a quantum number related to the orientation of an orbital?
There is only one way in which a sphere (l= 0) can be oriented in space. Orbitals that have polar (l= 1) or cloverleaf (l= 2) shapes, however, can point in different directions. We therefore need a third quantum number, known as the magnetic quantum number(m), to describe the orientation in space of a particular orbital.
How are quantum numbers related to electron configurations?
Energy must therefore be absorbed to excite an electron from an orbital in which the electron is close to the nucleus (n= 1) into an orbital in which it is further from the nucleus (n= 2). The principal quantum number therefore indirectly describes the energy of an orbital. The angular quantum number(l) describes the shape of the orbital.
