When two different atoms form a covalent bond, the electrons are not always shared equally. The atom with higher electronegativity tends to attract the bonding electrons more strongly, becoming partially negative (\u03b4\u207b), while the other atom becomes partially positive (\u03b4\u207a). This creates a polar covalent bond, and the molecule has a dipole moment pointing toward the more electronegative atom.<\/p>\n\n\n\n<p>Electronegativity values (Pauling scale):<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Bromine (Br): ~2.96<\/li>\n\n\n\n<li>Iodine (I): ~2.66<\/li>\n<\/ul>\n\n\n\n<p>Since bromine has a higher electronegativity than iodine, bromine attracts the bonding electrons more strongly than iodine.
