When an atom of H and an atom of Cl bond together:
a) the H will be partially positive, because it has
higher electronegativity than Cl.
b) the H will be partially negative, because it has
higher electronegativity than Cl.
c) the Cl will be partially positive, because it has
higher electronegativity than H.
d) the Cl will be partially negative, because it has
higher electronegativity than H.
