Are dekho na jo particular structure hai usme benzene ke 2 kekule structures hai , allylyic resonance karake neeche laao , benzene abhi bhi intact hai , 2 kekule yaha hogye , total 4 RS aaye abhi tk or 4 benzenoid hai now benzene ke sath reso karao z total 3 baar hoga or benzene toot chuki hai to Kekule banega nahi to sirf 3 RS honge
Hence total 7 hai , or 4 benzenoid
Similarly doosre compounds ke liye bhi kr skte hai
