valence bond theory
How many unhybridized p-atomic orbitals are there on an sp2
1 remaining p orbital
How many unhybridized p-atomic orbitals are there on an sp hybridized carbon atom?
2
free rotation
single bonds, sigma
sp3d2 hybridization
six degenerate sp3d2 orbitals octahedral
Resonance
the bonding in molecules or ions that cannot be correctly represented by a single Lewis structure
the number of standard atomic orbitals combined=
the number of hybrid orbitals formed
sp2 hybridization
trigonal planar three degenerate sp2 orbitals combination of 1 s orbtial and 2 orbitals
When does bonding occur?
when one hybridized orbital on one atom overlap with the unhybridized p orbital of another
what are the two ways orbitals can overlap to form bonds?
sigma or pi bonds
valence bond theory
chemical bond results from an overlap of standard atomic orbitals or a hybridized blend of these orbitals
rotation restricted
double bond (sigma + pi)
sp3d hybridization
five degenerate orbitals trigonal bipyramidal
sp3 hybrid orbitals
four degenerate orbitals tetrahedral
sigma bonds
head to head overlap electron density about the bond axis
hypridization
mixing of atomic orbitals to make a new set of degenerate orbitals as atoms approach each other to form bonds
sp hybrid orbitals
mixing the s and p linear 180 two degenerate orbitals
degenerate
orbitals with the same energy
pi bonds
side to side overlap electron density above or below the bond axis
bond rotation
sigma bonds point along the bond axis whereas pi bonds interact above and below the bond axis
