Which of the following compounds is aromatic?

Click For Summary
SUMMARY

The discussion centers on identifying aromatic compounds based on Huckel's rule, specifically the 4n+2 π electron criterion. Options A, B, C, and D were evaluated, with B and C deemed antiaromatic due to having 8 and 12 π electrons, respectively. The user expressed uncertainty about the planar nature of Option A, suggesting it may not be aromatic due to angular strain. Ultimately, the user seeks clarification on which option is aromatic, indicating a need for further analysis of the compounds presented.

PREREQUISITES
  • Understanding of Huckel's rule for aromaticity
  • Knowledge of π electron counting in organic compounds
  • Familiarity with molecular geometry and planarity
  • Basic concepts of hybridization and orbital theory
NEXT STEPS
  • Study Huckel's rule in detail, focusing on the 4n+2 π electron requirement
  • Learn about the characteristics of antiaromatic compounds
  • Explore molecular geometry and its impact on aromaticity
  • Investigate the role of unhybridized p orbitals in determining aromaticity
USEFUL FOR

Chemistry students, organic chemists, and educators seeking to deepen their understanding of aromatic compounds and the principles governing their stability and structure.

1. Homework Statement : please refer to the picture attached

Homework Equations

: [/B]A compound is aromatic if it is planar and it satisfies Huckles 4n+2 Π electron rule.

The Attempt at a Solution

: [/B]
Option A is not correct...I don't know why...just speaking from intuition..probably its not planar due to angular strain..I don't know..
Option B is also not correct because we have 8Π electrons which makes it anti aromatic.
Option C also is incorrect as we have 12 Πelectrons making it antiaromatic.
Same is true for Option D.
Then which one is correct? Is it option A as it is the only option I discarded based on intuition.

Where are the unhybridized p orbitals in that molecule?
