On what points can we identify the structure of this molecule? I have found out that since its frequency is just less than 3000 cm¹ it is an alkane. Also, the approximate value of the chemical shift is near 7.2, hence it is aromatic. But what I did not get was the meaning of two peaks at 7.2 and the shifts at 2.9 and 2.1.
