This is aromatic compound , because according to huckel's aromatic rule "Aromatic compound follows(4n+2) π rule{ where n should be whole number .}
According to this rule (4n+2) π should be equal to total π electrons present in the compound
Total π electrons here = 14 ( because there are 7 double bonds , 1 double bond contain 2π electron)
Hence ,
(4n+2) π = 14 π
4n = 14-2 = 12
4n =12
n = 12/4 = 3 ( which is whole number ) hence it follows huckel's aromatic rule . Hence this compound is Aromatic in nature.
