Question

In a covalent bond between two atoms, the more electronegative atom will attract more electron density toward itself, causing a polar bond. The more electronegative element is the negative pole, whereas the less electronegative element is the positive pole. The direction of the dipole is always toward the more electronegative element. This is often inflicated by an arrow, as shown in the figure. (Figure 1) The magnitude of the bond polarity is the difference in electronegativity values of the atoms. For example, in the molecule Cl2, the CICI bond is nonpolar because there is no difference in electronegativity between two atoms of the same element. In the CIBr molecule, However, the C1 Br bond is polar because Cl and Br have different electroneaativitv values. A CI I bond would be more polar than a C1 Br bond because there is a greater electronegativity difference between Cland I than between CI and Br.
