Which of the following is aromatic?

Question

Aicharya · Accepted Answer

Aromaticity can be predicted by the use of Huckle's rule which says that $(4 n+2) \pi$-electrons are required in delocalisation system to give it aromaticity. $(4 n+2) \pi$ electrons means $2,6,10 \ldots \ldots \pi$ electrons.

for delocalisation $=6$ $\therefore$ It is expected to be aromatic.
