Web4 apr. 2024 · Although covalent bonds do not result in charges, oxidation states are still useful. They label the hypothetical transfer of electrons if the substance were ionic. Determining the oxidation states of atoms in a covalent molecule is very important when analyzing "redox" reactions. Webcovalent compounds exist as gases liquids or soft solids because they have weak Van der Waals forces of attraction between their molecules Ashish Kumar Sahoo PhD in Chemistry Author has 190 answers and 322.1K answer views 5 y This is because covalent bonds are directional in nature.
