Interpretation:
The difference in local magnetic field when applied magnetic field is
Concept introduction:
Many nuclei and electrons have spin, due to this spin magnetic moment arises. The energy of this magnetic moment depends on the orientation of the applied magnetic field. In NMR spectroscopy, every nucleus has a spin. There is an angular momentum related to the spin. The difference between its resonance frequency and that of reference standard is known as the chemical shift of a nucleus. Tetramethylsilane is taken as reference. All nuclei experience different applied magnetic field due to varying chemical environment. Local field is the field experienced by the nuclei that is completely different from the applied magnetic field.

If 2 products are made, list which should be “major” and “minor” *see attachedarrow_forwardNucleophilic Aromatic Substitution: What is the product of the reaction? *see imagearrow_forward
- Show the correct sequence to connect the reagent to product. * see imagearrow_forwardThe answer here says that F and K have a singlet and a doublet. The singlet and doublet are referring to the H's 1 carbon away from the carbon attached to the OH. Why don't the H's two carbons away, the ones on the cyclohexane ring, cause more peaks on the signal?arrow_forwardDraw the Birch Reduction for this aromatic compound and include electron withdrawing groups and electron donating groups. *See attachedarrow_forward
