Identify the compounds or ions from the following list that are fundamentally classified as non-arom — GOC and Organic Chemistry Basics Chemistry Question
Question
Identify the compounds or ions from the following list that are fundamentally classified as non-aromatic due to the presence of at least one $sp^3$ hybridized carbon atom interrupting the cyclic conjugation.
Answer: A,B
💡 Solution & Explanation
Cycloheptatriene and cyclopentadiene contain at least one $sp^3$ hybridized $CH_2$ group that lacks an unhybridized p-orbital, breaking the continuous $\pi$ -overlap. Cyclooctatetraene is non-aromatic due to a tub shape (non-planar). Benzene is fully aromatic.
