Verified step by step guidance1
Understand that a partial positive charge on an atom in a bond occurs when the atom is less electronegative than the atom it is bonded to. Electronegativity is the tendency of an atom to attract electrons towards itself.
Review the electronegativity values of the elements involved: Oxygen (O), Nitrogen (N), Hydrogen (H), Fluorine (F), and Chlorine (Cl). Typically, Fluorine is the most electronegative element, followed by Oxygen, Chlorine, Nitrogen, and Hydrogen.
Compare the electronegativity of Oxygen with each of the other elements in the bonds: O-N, O-H, O-F, and O-Cl. Determine which element is more electronegative than Oxygen.
Identify that in the bond where the other element is more electronegative than Oxygen, Oxygen will have a partial positive charge because the electrons are drawn more towards the more electronegative atom.
Conclude that the bond where Oxygen is bonded to a more electronegative element than itself will result in a partial positive charge on the Oxygen atom.
