Polar Covalent Bond: A covalent bond between atoms that differ in Electronegativity. The shared electrons are pulled closer to the more electronegative atom making it slightly negative and the other atom slightly positive. 10. The difference between structural and molecular formula is that the molecular formula writes the chemical symbol with subscripts while the formula indicates bonds. 11. Ionic bonds compare with covalent bonds, because covalent bonds are stronger that ionic bonds. Ionic bonds are formed by the attraction of an anion and a cation. A covalent bond is formed by the sharing of valence electrons. 12. Hydrogen bonds are interactions between positive poles and negative poles of polar molecules for example like water. Van der Waals interactions are between the positive nucleus of one atom and the negative electron cloud of neighboring atoms. 13. An example in a loving system of how molecular shape is critical is that molecular shape determines the function of a molecule. If something changes the shape of a molecule it will no longer function
