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
