WebShielding in H-NMR. Structural factors cause changes in the magnetic field experienced by the nucleus. As we have seen, this changes the resonance frequency and hence the chemical shift. The structural factors mean that different types of proton will occur at different chemical shifts. This is what makes NMR so useful for structure ... WebIn this lesson, we will learn: To recall the definitions of electron-withdrawing group (EWG) and electron-donating groups (EDG). To understand the effects of EWGs and EDGs on nucleophile and electrophile strength. To understand the underlying electronic effects that produce these properties. To apply mesomeric and inductive effects to predict ...
