Indapamide may be used in the treatment of hypertension and heart failure. Its structure is shown below: Q1. Using your knowledge of NMR spectroscopy, draw the THREE expected splitting patterns for the protons attached to the labelled atoms in the structure above (1, 2 and 3). You should indicate the estimated coupling constants on your diagrams in Hz, and indicate which protons cause signals to split. Can you please make sure to actually DRAW the three expected splitting patterns?

This is a part of a practice worksheet that asks me to use H-NMR, C-NMR, Mass Spectroscopy, and IR Spectrum to answer the questions being asked. It will not be collected, but I want to make sure I understand it for our quiz next week. Thank you so much. :)
what does having a DBE(double bond equivalent) of 6 indicate when working with spectroscopy graphs?
Can you explain spectroscopy? Let's start with NMR Spectroscopy. What is the difference between a proton being enantiotopic and homotopic? What does it mean for a proton to be shielded or deshielded? How do you determine J (the coupling constant)? What does 'coupling is mutual' mean? How is that translated on the NMS Spectroscopy spectrum? Does that have to do with the polarity of the molecule? Is there an easier way to explain that? When thinking about C-13 NRM Spectroscopy, what it meant by the statement, "the carbons cannot integrate"? When looking at an NMR Spectroscopy spectrum, how do you know which peak belongs to which proton? (The intensity of the peak and the ppm of the peak) P.S. These questions come from after watching a lecture. There is no graded assignment attached to these questions. I simply do not understand the material.
