Question

What intermolecular force(s) of interaction is(are) present between two molecules of dimethyl ether, CH₃OCH₃? I. London dispersion forces II. Dipole-dipole forces III. Hydrogen bonding

Quizplus · Accepted Answer

Dimethyl ether (CH3OCH3) exhibits London dispersion forces due to the temporary dipoles that can form in any molecule, regardless of its polarity. It also exhibits dipole-dipole interactions because it is a polar molecule, with the oxygen atom having a higher electronegativity than the carbon and hydrogen atoms, creating a permanent dipole. However, it does not have hydrogen bonding because it lacks a hydrogen atom directly bonded to a highly electronegative atom such as nitrogen, oxygen, or fluorine, which is a requirement for hydrogen bonding.
