Dipoles

Postby Karolina herrera1F » Tue Jul 16, 2019 10:10 pm

Are Dipoles polar? Can they be Dipoles and also have a hydrogen bond?

Dipole-Dipole interactions occur when polar molecules are attracted to eachother's opposite charges. Hydrogen bonds are a type of dipole-dipole interaction and also rely on polarity

I am not going to repeat what hanna said, but to answer your question about hydrogen bonds. Hydrogen bonds only occur with N, O, F that is attached to a hydrogen and it is a type of dipole dipole interaction.

Hydrogen bonging is a special form of dipole-dipole bonding, which is the strongest.

Dipoles are usually polar, and they become a hydrogen bond any time an FON is attached to an H. However, there could be dipole interactions present like in CO2 or CCl4 however these interactions would cancel and the molecule would be considered nonpolar based on shape.

Dipoles are usually polar, but I think the VSEPR shapes determine if the dipoles can cancel out. If the dipoles can be canceled out, for example, tetrahedral, then the molecule will not be polar.

Dipoles are polar unless they cancel out in elements such as CCl4. Hydrogen bonding is a type of dipole-dipole interaction that occurs when F, O, C, and N are bonded to a hydrogen.

Only polar bonds have dipoles, and only dipoles form the hydrogen bonds will form.
