Dipole moment is just one of facets of solvent polarity, together is famed in HPLC separation analytical method where the following impacts take part:
Dipole moment interaction, permanent and inducedThe above for the totality molecule and also for details bondsElectron pair donorElectron pair agree (including $\ceH+$ donation)
Depending ~ above solute molecule specifics, the solvent polarity order is variable, as miscellaneous molecules have various responses to above interactions.
You are watching: Is acetone more polar than ethanol

The bond dipole μ is given by:
$ \mu =\delta \,d$.
The bond dipole is modeled together +δ — δ- with a distance d between the partial charges +δ and δ-. It is a vector, parallel come the shortcut axis, pointing from minus come plus, as is standard for electric dipole moment vectors.
In her case, acetone has a greater dipole moment than ethanol because it has a carbonyl group an ext towards the center and also thus acetone has lesser boiling suggest than ethanol.
The an interpretation is native Wikipedia, : https://en.m.wikipedia.org/wiki/Bond_dipole_moment
EDIT : Alcohol hydrogen bonding is the significant effect here, as in the instance of water. (by
