What does the average electronegativity tell me? - Quora

WebAn electronegative atom pulls valence electrons away from the atom and effectively decreases the electron density around the nuclei. Thus, a lower value of B0 is needed to reach the resonance frequency of the nucleus. The Cl atom removes enough electron density to shift the frequency of an adjacent proton from δ 0.9 to δ 3.4 ppm. WebA polar bond is caused by the uneven distribution of the bonding pair of electrons due to the differing electronegativities of the two atoms. A polar bond causes what is known as a dipole.
