In the acetyl ferrocene NMR spectrum, how could you tell which peak(s) belong to

Question

In the acetyl ferrocene NMR spectrum, how could you tell which peak(s) belong to the acetylated ring, and which peaks belong to the non-acetylated ring?
In the diacetylferrocene NMR spectrum, how could you predict which peak corresponds to the Hs adjacent to the acetyl group, and which peak corresponds to the aromatic Hs further away from the acetyl group?

Explanation / Answer

1) Acetyl ferrocene acetyl contain aromatic ring proton are have high delta values compare with non acetylated ring.

2) diacetylferrocene NMR adjust to acetyl peak aromatic peak will give more value (near 7.43 doublet), away of the acetyl group hydrogen peak NMR value 6.50 (doublet of doublet), another hydogen will give 6.40 ( doublet)
