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. WebJul 20, 2024 · Explanation: You'll need to take the difference between the electronegativity value of the two atom. Their bond polarity is determined according to the range it falls in: Nonpolar covalent: Electronegativity difference < 0.5. Polar covalent: Electronegativity difference is 0.5 - 1.6. Ionic: Electronegativity difference >2.
