Conjugated Systems: Where Resonance Comes to Life

The video tutorial explains the concept of Pi conjugation, focusing on the stability of 1/3 butadiene compared to 1/2 butadiene. It discusses how Pi electrons in conjugation with Sigma electrons lead to the formation of resonating structures, enhancing stability. The tutorial introduces the concept of resonance hybrid, a hypothetical structure representing the resonance phenomena, and provides an orbital view for better understanding.

How are the four Pi electrons distributed over the carbon centers in 1/3 butadiene?

What is a resonance hybrid and how does it relate to butadiene?
