2. Huckel rule states that the compound which follows $(4\mathrm{n}+2)\mathrm{\pi }{\mathrm{e}}^{-}$ where $\mathrm{n}=$number of $\mathrm{\pi }$ electrons are called aromatic
3. The $2{\mathrm{\pi e}}^{-},6{\mathrm{\pi e}}^{-},10{\mathrm{\pi e}}^{-}......$ are called aromatic

Explanation for correct option:

(A)

According to Huckel's rule, the above compound formed is aromatic. Hence option A is correct.

(B)

According to Huckel's rule, the above product formed is aromatic. Hence option B is correct.

Explanation for incorrect option:

(C)

According to Huckel's rule, the above formed compound is Anti-aromatic. Hence option C is incorrect

(D)
