Concept introduction:
According to the variation theory, the lower the energy of a system the better is the approximation. Variation theory is based on the fact that any test system has average energy equal to or greater than the ground state energy of that system. The advantage of the variation theory is that any wavefunction can be taken for any test system.

- Nucleophilic Aromatic Substitution: What is the product of the reaction? *see imagearrow_forwardShow 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_forward
