Chapter 1: 1.5 Resonance Structures (Delocalization of Electrons) Flashcards
1
Q
Define:
Delocalized system
A
One where lone pairs and/or double/triple bonds can be “localized” over more than one location
2
Q
Define:
Resonance structure
A
One in which you can depict molecules with two or more structures
3
Q
What will resonance structures look like?
A
Will have delocalized bonds and are indicated by a double headed arrow
4
Q
What should you NEVER do in a resonance structure?
A
Break a sigma bond
5
Q
What do dotted lines in bonds mean?
A
Indicate “partial” bonds and are found with resonance structures and delocalized bonds
