please solve both the above parts of the question given and solve as soon as possible.

Subject is : Mass spectrometry (NMR)

Assign all the peaks and state for each peak the main effect responsible for the observed chemical shift (note: the H atoms attached to the O atoms is not visible in the spectrum. The spectrum was recorded in CDCl3 and traces of acetone (2ppm) and TMS (0ppm) are also visible). Make the assignment by completing the assignment table that is included in the separate answer book document. [12 marks] Identify within the same 1H NMR spectrum in Figure 1 an example of higher order (i.e., roofing) effect and state why this is observed. Identify a pair of chemically equivalent but magnetically non-equivalent hydrogen atoms, and state why they are magnetically non-equivalent. Figure 1
