Dipole dipole vs LDF

[Claire_Kim_2F]

I was wondering if Dipole Dipole and ldf were the same kind of force?

[Chem_Mod]

Dipole dipole and LDF are both intermolecular forces. However, dipole dipole only occurs with two polar molecules. LDF is present in practically all molecules. Dipole dipole intermolecular force is also stronger than LDF.

[Sahaj Patel Lec3DisK]

LDF are intermolecular forces that naturally occur between most polar (or induced molecules). They will always be present, however for certain polar molecules, in the moment they interact that moment of interaction is called a dipole dipole moment. Hope this helps!

Hi! Maybe you were thinking of Induced-Dipole — Induced-Dipole attractions? Dr. Lavelle did say those and London Dispersion Forces are similar.

[Shruti Kulkarni 2I]

Dipole-dipole and LDF forces are similar as they occur from the dipoles of molecules. However, dipole-dipole forces occur in polar atoms/molecules while LDF forces occur spontaneously in any atom/molecule as a result of a shift in its electron density.

London Dispersion forces happen between every type of molecule, because it has to do with the very brief polarizability of an electron field. Dipole-dipole forces have to happen between two polar molecules, because the unequal covalent bond makes the opposite ends of each molecule attract, pulling the electron field into its dipole-type shape

[Allan Nguyen 2G]

Dipole dipole and LDFs are both intermolecular forces. LDFs occur between every atom and molecule in intermolecular forces, while dipole dipole only occurs between polar molecules that are dipole.

[DMaya_2G]

LDF happens between nonpolar molecules, and they are extremely weak. Dipole-dipole forces happen between polar molecules, therefore they have a stronger bond, since it has a slight charge that are very similar to ions.

LDF happens between all molecules I believe, but dipole dipole will happen between polar ones. LDF only happens when symmetric molecules bind or molecules of the same molecular formula bind.

[Crystal Pan 2G]

These are both intermolecular forces, but LDF and dipole-dipole are different. LDF could be used interchangably with induced dipole-induced dipole/van der waals forces/dispersion.

[Victoria Dao 3G]

I was a bit confused on this too, but just remember that nonpolar molecules can ONLY exhibit LDFs, while polar molecules can exhibit more than one intermolecular force, including LDFs.
