The chemical shift of the ch3 protons in diethylether is δ = 1.16 and that of the ch2 protons is 3.36. what is the difference in local magnetic field between the two regions of the molecule when the applied field is (a) 1.9t, (b) 16.5 t?

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

The answer is b because c don't explain why the moths are on them and it isn't a because as we know only one species of moth does this
