Based on this IR what are the relevant peaks?

Into how many peaks will the signal for attached of the labeled protons be split ?

What’s the purpose of NMR splitting tree

The following NMR corresponds to the molecule depicted below ran without reference. Assign the carbons to the peaks of the spectrum. Do this approximating the shift based on the atoms the Cs are attached to.  The question & answer options are attached.

Please correct answer and don't use hend raiting

In the Labster experiment, there are only singlet peaks seen in 13C- NMR. Do you think we will see peak splitting in 13C- NMR? O Splitting patterns depend.on the frequency of the machine O Splitting happens but not in these examples O No, the carbon's do not couple O You don't see splitting patterns in any NMR spectra

How does H-nmr shift work ? like how do i know which line goes where ?

Choose the frequency of a peak that is most likely to correspond to an sp² C-H stretch of an aldehyde in an IR spectrum. A) 3450 cm-¹ B) 3100 cm-¹ C) 2800 cm-¹ D) 2250 cm-¹ E) 1450 cm-¹
