This relationship between lower charge densities giving rise to lower basicity also applies to lone pairs that can be delocalized into a larger pi systemthrough resonance. You may … Visa mer Previously, we’ve seen how to evaluate the basicity of amines by examining the pKa of its conjugate acid (pKaH). (The higher the pKaH, the stronger the base). But we haven’t yet dug into the key concepts that help us evaluate, for … Visa mer We’ve seen that resonance tends to decrease basicity (Factor 2) and so do inductive effects (Factor 3). That said, how do you explain why amides are significantly less basic than amines? Is it resonance? Is it … Visa mer You may recall that electron withdrawing atoms (e.g. F or Cl) or functional groups (e.g. NO2) tend to increase acidity, by slurping away electron density from the conjugate base. … Visa mer Back to our amide example. Why is it less basic? The first factor is that an electron-withdrawing oxygen is present, which can remove some of the electron density from nitrogen. However, this is outweighed by the fact that there is … Visa mer Webbπ backbonding, also called π backdonation, is a concept from chemistry, in which electrons move from an atomic orbital on one atom to a π* anti-bonding orbital on …
