Chapter 1.9: Molecular Orbitals for Delocalized Systems

Question 1

When do pi delocalization occur and why is it important?

Answer 1

 Can only have pi delocalization if all the atoms involved have a 2p orbital
 Stabilization due to pi delocalization

Question 2

Define conjugation

Answer 2

a situation in which the multiple bonds are separated by a single bond. Alternatively, a series of overlapping 2p orbitals

Question 3

Define delocalization

Answer 3

the spreading of electron density over a large volume of space

Question 4

What is the spreading of electron density over a large volume of space?

Answer 4

delocalization

Question 5

What is a situation in which the multiple bonds are separated by a single bond. Alternatively, a series of overlapping 2p orbitals?

Answer 5

conjugation
