Trailer Weight Ratings-also known as tow ratings or tow limits-are available here for new tow vehicles sold in North America. Some results also include additional tow-related notes specific to that particular make and model. Search by year, make, and model or trailer weight.
An ion-dipole force is a force between an ion and a polar molecule. A hydrogen bond is a dipole-dipole force and is an attraction between a slightly positive hydrogen on one molecule and a slightly negative atom on another molecule.Hydrogen bonds are important in the properties of water and in certain biological molecules, such as proteins.n ion-dipole force is a force between an ion and a polar molecule. A hydrogen bond is a dipole-dipole force and is an attraction between a slightly positive hydrogen on one molecule and a slightly negative atom on another molecule.
For example, H-Cl has a dipole. The electrons spend more of their time near the Cl atom (the red end in the diagram below). A dipole-dipole interaction is the attraction between two polar molecules. When they approach each other, the negative end one molecule attracts the positive end of the other.
