How do dipole-dipole forces cause molecules to be attracted to one another?

Question

Emilia Alvarez · Accepted Answer

oppisites attracts

So dipole - dipole forces could be the forces between water molecules. This attraction occurs because the small difference in charge (not really charge difference - happens because the large difference in electronegativity). Therefore oxygen has a negative charge and hydrogen has a positive charge, thereby making it possible for the water molecules to make interactions to each other.

This is illustrated on the picture above

undefined Dipole-dipole forces occur between polar molecules due to the attraction between the positive and negative ends of the dipoles. This attraction leads to the alignment of molecules with opposite charges, resulting in a net attractive force between them.

Delilah Anderson · Answer

undefined Dipole-dipole forces occur between polar molecules, where one end of the molecule has a partial positive charge and the other end has a partial negative charge. These forces cause the positive end of one polar molecule to be attracted to the negative end of another polar molecule. As a result, the molecules align themselves in a way that maximizes the attraction between opposite charges, leading to an overall attractive force between the molecules. This attraction contributes to the cohesion of substances and can affect their physical properties such as melting and boiling points.

undefined Dipole-dipole forces are a type of attraction between two molecules that have a permanent dipole moment. A dipole is created when there is an uneven distribution of charge within a molecule, resulting in a positive end and a negative end.

Here are the steps that explain how dipole-dipole forces cause molecules to be attracted to one another:

1. First, we need to understand that opposite charges attract each other. In a molecule with a dipole, the positive end of one molecule is attracted to the negative end of another molecule.

2. When two molecules with permanent dipoles approach each other, the positive end of one molecule is attracted to the negative end of the other molecule.

3. This attraction causes the molecules to come closer together, which leads to an overall decrease in potential energy. This decrease in potential energy is favorable and contributes to the overall attraction between the molecules.

4. As a result, the molecules with dipole-dipole interactions tend to stick together, forming a stronger bond between them.

In summary, dipole-dipole forces cause molecules to be attracted to one another because opposite charges attract each other, and the resulting attraction between positive and negative ends of molecules leads to a decrease in potential energy, resulting in the bonding of the molecules.
