Electron Delocalization

Question 1

Resonance structures

Answer 1

weighted average of a set of Lewis structures

Question 2

Resonance hybrid

Answer 2

the actual electronic structure of the molecule; molecule does not fluctuate between resonance structures it is the resonance hybrid

Question 3

Features of resonance structures

Answer 3

hybridization assigned to one resonance structure must be the same as all the other resonance structures (because it describes 1 molecule)

Question 4

aromatic compounds

Answer 4

containing structures and exhibit bonding that must be describes using resonance structures

Question 5

Which resonance structures have the most weight?

Answer 5

all zero FC, then lowest non zero FC, then making sure that all FC are on most electronegative atoms
