Question Answer
VSEPRValence shell electron pair repulsion
VSEPR molecular geometrieslinear, trigonal planar, tetrahedral, trigonal bipyramid, octahedron
dipole moment equationm=Q*r(charge x distance between charges)
Valence bond theorybonds are formed by sharing of e- from overlapping atomic orbitals
Hybridizationmixing of two or more atomic orbitals to form a new set of hybrid orbitals
Number of hybrid orbitals is equal to number ofpure atomic orbitals used in the hybridization process
Covalent bonds are formed byOverlap of hybrid orbitals with atomic orbitals & Overlap of hybrid orbitals with other hybrid orbitals
how to predict hybridization of an atom?
Single bond1 sigma bond
Double bond1 sigma bond and 1 pi bond
Triple bond1 sigma bond and 2 pi bonds
Molecular orbital theorybonds are formed from interaction of atomic orbitals to form molecular orbitals
paramagnetic vs diamagnetic?
A bonding molecular orbital has lowerenergy and greater stability than the atomic orbitals from which it was formed
An antibonding molecular orbital has higherenergy and lower stability than the atomic orbitals from which it was formed

Question Answer
Delocalized molecular orbitals are not confined between two adjacent bonding atoms, but actuallyextend over three or more atoms
