antibonding molecular orbital
|
A molecular orbital in which the energy of the electrons is higher than that of the parent orbital electrons
|
|
|
bonding molecular orbital
|
A molecular orbital in which the energy of the electrons is lower than that of the parent orbital electrons
|
|
|
heteronuclear diatomic molecule(s)
|
A molecule composed of two atoms of different elements
|
|
|
homonuclear diatomic molecule(s)
|
A molecule composed of two identical atoms
|
|
|
hybrid orbital(s)
|
An orbital formed by mixing two or more atomic orbitals
|
|
|
isomer(s)
|
Two or more compounds with the same molecular formula but different arrangements of atoms
|
|
|
molecular orbital theory
|
A model of bonding in which pure atomic orbitals combine to produce molecular orbitals that are delocalized over two or more atoms
|
|
|
orbital hybridization
|
The combination of atomic orbitals to form a set of equivalent hybrid orbitals that matches the electron pair geometry of the compound
|
|
|
orbital overlap
|
Partial occupation of the same region of space by orbitals from two atoms
|
|
|
pi (π) bond(s)
|
The second (and third, if present) bond in a multiple bond; results from sideways overlap of p atomic orbitals
|
|
|
sigma (σ) bond(s)
|
A bond formed by the overlap of orbitals head to head, and with bonding electron density concentrated along the axis of the bond
|
|
|
single bond
|
A bond formed by sharing one pair of electrons; a sigma bond
|
|
|
valence bond theory
|
A model of bonding in which a bond arises from the overlap of atomic orbitals on two atoms to give a bonding orbital with electrons localized between the atoms
