The resonating structures of aniline (\( C_6H_5NH_2 \)) are as follows:
\[
\text{Structure 1:} \quad \begin{aligned}
\text{Delocalization of lone pair of electrons from the nitrogen into the benzene ring.}
\end{aligned}
\]
\[
\text{Structure 2, 3, etc.: \quad Draw the other resonance structures here.}
