1
New cards
Ī£ orbital
________: cylindrically symmetric about the bond axis; no nodal plane along the bond axis.
2
New cards
MO
In ________ theory, valence electrons are delocalized over the entire molecule, not confined to individual atoms or bonds.
3
New cards
relative energy ordering
The ________ is Ļ2pz
4
New cards
internuclear region
An electron in an antibonding MO will be excluded from the ________, and thus have a higher energy than if in an atomic orbital.
5
New cards
energy differential
If the ________ is small, then the molecule is not as stable.
6
New cards
š orbital
________ (bonding orbital): molecular orbital with a nodal plane along the bond axis.
7
New cards
relative energy ordering
The ________ is šāāā and šāāy
8
New cards
Bond order = ½ ( of bonding electrons
of antibonding electrons)
9
New cards
Ļ orbital
cylindrically symmetric about the bond axis; no nodal plane along the bond axis
10
New cards
1s
1s = Ļāā* (antibonding MO)
11
New cards
š orbital (bonding orbital)
molecular orbital with a nodal plane along the bond axis
12
New cards
2pā
2pā = šāāā*
13
New cards
2pįµ§
2pįµ§ = šāāįµ§*
14
New cards
š orbital (antibonding orbital)
MO with 2 nodal planes along the bond axis
15
New cards
An electron in a bonding MO will be
attracted to both nuclei, and will be lower in energy (more stable) compared to an atomic orbital for a single nuclei
16
New cards
An electron in an antibonding MO will be
excluded from the internuclear region, and thus have a higher energy than if in an atomic orbital
17
New cards
N molecular orbitals can be created from
N atomic orbitals
18
New cards
Molecular orbitals arise from
adding together (superimposing) atomic orbitals
19
New cards
A linear combination of atomic orbitals (LCAO) creates
molecular orbitals (bonding and antibonding orbitals)
20
New cards
Bond order =
½ (# of bonding electrons - # of antibonding electrons)
21
New cards
The relative energies of the Ļ2pz compared to the Ā šāāā or y orbitals depend on
the z value of the atoms
