Given is the NMR spectrum and molecule. Could you please help me explain the peaks? I am specially confused because it seems the peaks have merged so I am not sure what peaks to count together. On top of that there are multiple secondary alkanes, and I am not sure about their downshift order.

Here's what I am thinking so far:

 

1: triplet - not sure of the chemical shift value

2: doublet of triplet - between 1.2 - 1.7

3: triplet of triplet - between 1.2 - 1.7

4: triplet of triplet - between 1.2 - 1.7

5: triplet - 4

6: Singlet - (11-12)

7: Triplet - (1-5)

 

 

The spectrum is crap!

Your predictions are correct. 1 should be around 2,5 ppm.

But the spectrum shows only broad singlets, don't know what to make of this.

Request a new, better one, with resolved multiplets and integrals.
