Dipole dipole forces

Postby Jared_Yuge » Sun Nov 10, 2019 11:40 pm

What's the difference between dipole-dipole forces and induced dipole-induced dipole forces? I could not quite grasp this concept in the lecture

A dipole-dipole force is between two dipoles like HCl and HCl. A dipole-induced dipole is between a dipole and a nonpolar molecule. The dipole distorts the electron cloud of the molecule, so the electrons shifts around the nucleus, causing a partial positive and partial negative charge, that becomes attracted to the dipole.

A dipole-dipole force occurs when both compounds naturally have dipoles (HI). Induced dipoles occur when both molecules don't have a dipoles, and the induced dipole is caused by a random shift in the electron cloud.
