Bond between A and B can be represented by A \(\rightarrow\) B, A\(^+\)B\(^-\), A\(^-\)B\(^+\). If A is more electronegative than B, then least contribution to the actual structure comes from

C\(_6\)H\(_6\) consists of one ring, while naphthalene consists of two rings. Both of them are aromatic and obey the (4n+2) rule. Thus the number of \(\pi\)-electrons inside rings of C\(_6\)H\(_6\) and naphthalene are respectively
