Answer to Question #120191 in Inorganic Chemistry for Varsha

Question

The compound ph3(As)2Cl2Rh(C4H7) shows two peaks in 1HNMR spectra at 60degree but at 30degree it shows three peaks relative intensities 3:2:2.explain with mechanism

Answer 1

The number of peaks or resonances (signals) in the spectrum indicates the number of non-equivalent protons in a molecule. The relative intensities of the signals indicate the numbers of protons that are responsible for 

individual signals. The area under each peak is measured in the form of an integral line. The height of the steps of this line is proportional to the area under the peak and therefore indicates 

the number of protons.
