Dispersion forces in CH₃ CHO

Postby Mrudula Akkinepally » Sat Nov 14, 2020 10:46 pm

I can understand why CH₃ CHO has dipole-dipole forces, but can someone explain why it also has dispersion forces? I read the explanation that Sapling gave me but I still didn't understand.

Every molecule exhibits dispersion forces, although to different degrees. The nature of fluctuating electron densities where slight positive and slight negative regions are created occurs in all molecules and is what is responsible for dispersion forces. How polarizable the molecule is, which is determined by number of electrons and size of atoms, will determine the strength of the dispersion forces.

Just as what is said in the Dr. lavelle's lecture, London Dispersion Force always exists because electrons always exist, and electrons always fluctuate.
