Interpretation Introduction

Interpretation:

For the given equilibrium reaction, the favored side of equilibrium should be determined.

Concept introduction:

• The compounds having two $\text{C}\text{=}\text{C}$ π bonds are called dienes.

  Based on the proximity of $\text{C}\text{=}\text{C}$ bonds in dienes, they are classified into three.

  • Cumulated dienes: the $\text{C}\text{=}\text{C}$ bonds are located adjacent carbons.
  • Conjugated dienes: the $\text{C}\text{=}\text{C}$ bonds are separated by one σ-bond.
  • Isolated dienes: the $\text{C}\text{=}\text{C}$ bonds are separated by two or more σ-bonds.
• The conjugated dienes are more stable as compare to isolated dienes because the delocalization of π bonds is taking place, so this forms some stabilization energy in conjugated system.
• In an equilibrium reaction, the side of most stable compound is favored.

To determine: the favored side of equilibrium for the given equilibrium reaction.
