Correct order of bond length in two organic molecules

Click For Summary
SUMMARY

The discussion centers on the bond length comparison between two organic molecules, specifically identifying the relationship between their stability and bond lengths. The conclusion reached is that molecule x, which participates in resonance, is more stable than molecule y, leading to the determination that x has a shorter bond length than y, thus confirming option C (x PREREQUISITES

  • Understanding of resonance in organic chemistry
  • Familiarity with bond length and stability concepts
  • Knowledge of Hückel's rule and π electron systems
  • Basic principles of molecular orbital theory
NEXT STEPS
  • Study the application of Hückel's rule in various organic compounds
  • Explore the relationship between resonance and bond length in detail
  • Learn about molecular orbital theory and its implications for stability
  • Investigate the effects of delocalization on bond lengths in different molecular structures
USEFUL FOR

Chemistry students, organic chemists, and educators seeking to deepen their understanding of molecular stability and resonance effects on bond lengths.

Homework Statement

: [/B]The correct relation is:
A. x=y
B. x>y
C. x<y
D. None.
Please refer to picture attached.

Homework Equations

: [/B]As stability increases, bond length decreases. When a Π bond is delocalised i.e it takes part in resonance, stability increases.

The Attempt at a Solution


I think x takes part in resonance.
Hence x is more stable than y.
Thus x<y i.e C is correct option.

Do you know the Hückel rules?

yeah, I know..the 4n + 2 Π electron rule...right?
 
Yes, do you see how to apply it here?

no..
 
more resonance = longer bond

more resonance = longer bond

Compared to what?
