Expert Solution
Step 1

The chemical shift of the protons in the 1H NMR spectrum depends upon the shielding and deshielding of that proton. 

If the proton is deshielded then the peak will appear at downfield and chemical shift value will be high. 

If the proton is shielded then the peak will appear at upfield and chemical shift value will be low.
