Compare the stability of two conjugated dienes, and two nonconjugated dienes, each with the formula C7H12 and the base name hexane. Which type is the most stable and which is the least stable according to your data? For one of the conjugated dienes, determine the bond lengths of each C-C single bond. Indicate which is the shortest and explain why it is using a resonance structure
