Ch 9 - Bonding Flashcards
1
Q
Polar Covalent Bond
A
the greater the difference in electronegativity the more polar a bond is
2
Q
Resonance
A
must draw two Lewis structures.
the true structure of something like (O3) is actually an average of both structures.
3
Q
Formal Charge
A
FC = valence e - nonbonding e - 1/2 bonding e
4
Q
Bond Length
A
the more electrons two atoms share the short the bond.
Decreases from left to right across the periodic table.
Increases down the periodic table.
longer bonds are weaker.
