Chemistry - GOC Question with Solution | TestHub

Explain the question : To find out the non aromatic compound

Concept : This question is based on aromaticity, Huckel's rule, planarity and conjugation. Solution:

Aromatic compounds $⟶4n+2\pi$ e- containing ( $n=0,1,2,3\dots .$. ) cyclic, planar , conjugated are aromatic

Antiaromatic compounds $\to 4\mathrm{n}\pi \mathrm{e}(\mathrm{n}=1,2,3\dots .$.$),cyclic,planarconjugated$

Non-aromatic compounds → not satisfying planarity or conjugation conditions.

Non-Aromatic

Non-Aromatic

Anti-Aromatic $4\pi {\mathrm{e}}^{\ominus }$ cyclic planar

Compound in option (1) & (2) are non-aromatic because of presence of non planar ${\mathrm{sp}}^3\mathrm{C}$. Final answer : Option (A), (B).
