Need help on these spectroscopy questions Questions 3-5 use top spectrum questions 6-8 use bottom spectrum

I am stuck on this NMR spectroscopy stuff about the compound Cnggo 120 [Ell] m mc) a Relative Intensity3 EU 3. What is the expected ratio between the peaks at 122 and 123 and why? 4. What fragment is lost to produce the base peak at 107? such a stable cation. 6. Select all of the following that are present in this molecule, given this NMR spectrum. Pickfrom the choices below. Note that a proton is missing! You should know why that is if you havesolved the structure correctly and you remember what was discussed about this type ofcompound and its NMR below. Signa s 3.0 1.1 mat about 2'6 ppm C pp7.0 ppm BA 10 8 6 4 2 0 Choice options for question 6: O-H of acid, 0-H of alcohol, C—H of aldehyde, Benzene CH, AlkeneCH, CH adjacent to W], etc., CH in ally position/benzyl position/adjacent to C=O, t—butylgroup, isopropyl group, ethyl group (not part of another chain), methyl group (not part ofanother chain 7. Draw the structure of the molecule using line structure and label each type of proton with anQ, or C from the spectrum above. 8. Sketch a 13C spectrum of your compound. Redraw your structure and put numbers 1,2,3 etc.on the structure and on the 13C spectrum to show which peak corresponds to which carbon orcarbons
