a) Draw the below structure and answer the following questions. CI CH2COCH2CH3 i. Identify the chemically equivalent protons in the structure. Explain your answer. ii. Mention how many peaks you would expect in the HNMR spectrum of the compound. Explain the position of each peak in the spectrum. iii. Mention what would be the splitting pattern of each peak with proper explanation. iv. Draw the HNMR spectrum of the compound. b) Explain why the delta/ ppm scale was introduced instead of Hz in NMR analysis with example.
