1
Q
shape and size of a molecule is determined by
A
bond angles and lengths
2
Q
what sort of charge do electron domains have?
A
negative. therefore they repel each other, creating shape.
3
Q
constructive interference
A
when two electrons overlap and form shared electron density
4
Q
pi bonds are characterized by (2)
A
- side to side overlap
- electron density above and below the internuclear axis.
5
Q
bond order
A
the measure of stability of a covalent bond
6
Q
the three rules for molecular orbitals
A
1) # MO formed = # atomic orbitals
2) Atomic orbitals combine most effectively with other atomic orbitals of similar energy
3) Effectiveness of orbital combination is proportional to their overlap
