WebNov 7, 2015 · Electronegativity is a parameter used to describe atomic properties. A molecule may contain electronegative atoms, but we do not speak of its electronegativity. Explanation: Electronegativity is conceived to be the ability of atom in a molecule to polarize electron density towards itself. WebMar 30, 2024 · To determine whether or not the molecule is polar, you have to look at the partial charge vectors on the two bonds in the molecule. First, there are two electron pairs on the molecule, which means there will be a large negative partial charge vector in that direction. Next, oxygen is more electronegative than hydrogen and will hog the electrons.
