Which type of bond will most likely be found in HBr given that the electronegativity of hydrogen is 2 point 2 0 and the electronegativity of bromine is 2 point 9 6 ?

The electronegativity difference is 2.96 − 2.20 = 0.76. This difference means bromine attracts the shared electrons more strongly than hydrogen, so the electrons are shared unequally. HBr therefore has a polar covalent bond, choice A.
