4. Look at the structure of the product (provided), 3 hydrogens are labelled (H₁, H₂ and H.). While H₂ may look simple on the ¹H NMR spectrum that you obtained (due to low resolution), it actually has a more complex splitting pattern. Create a tree diagram showing the splitting of H₁. Hint: H₁ is diastereotopic proton, assume JAB > Jac and assume no long range (>3 bond) coupling. AC Hb Ha I Hc

Long-range coupling between protons more than two carbon atoms apart is sometimes observed when bonds intervene. An example is found in 1-methoxy-l-buten-3-yne. Not only does the acetylenic proton, Î—a, couple with the vinylic proton Hb, it also couples with the vinylic proton Hc, four carbon atoms away. The data are: Construct tree diagrams that account for the observed splitting patterns of Î—a, Hb, and Hc.

ORGO II NMR please help fill out the chart and label. my unknown is C6H10O.
I’m assuming this is an alkene, but I’m lost on a few things. (I provided the mass spec, H and C NMR, and the IR spectra for this compound in the pictures). Looking at the C-NMR what can be interpreted from the chemical shifts? And what can be interpreted from the major peaks shown on the mass spectrum? I believe the compound is cyclohexene, but am I right? And if it is drawn out how does the figure relate to the H and C spectra?
A. Below is a “Name Reaction” - Clemensen reduction. Describe how the IR spectrum could be used to tell if the reactions had been successful. Provide approximate wave numbers and the corresponding functional groups for the key absorption bands and/or peaks in IR. You might want to describe from two aspects: which peak(s) of what functional group(s) should appear in the IR of the product (that is different from the reactant); which peak(s) of what functional group(s) should disappear in the IR of the product (that is present in the reactant B. For the Clemensen reduction (same reaction), describe how the 1H NMR spectrum could be used to tell if the reactions had been successful. Provide approximate chemical shifts and the integral and the “splitting” of the “unique” in the NMR spectrum. You might want to describe from two aspects: which peak(s) should have a change in chemical shift(s); which peak(s) should have a change in integral; which has a splitting change; which peak(s) will be…
