The dipole moment in acetone is greater than in the acetate group and therefore acetone is more polar (polarity index of 5.1) than ethylacetate (polarity index 4.4).
CH3COCH3 as opposed to CH3COOCH2CH3
While both compounds contain a double bond to oxygen (as highlighted above), which creates a strong dipole moment (i.e. polarity in the molecule) the adjacent oxygen in the acetate group attracts electrons to itself reducing the electron density in the double bonded oxygen thereby reducing the molecule's polarity.
Acetone is more polar than ethyl acetate because it has a higher dipole moment due to the presence of a carbonyl group. The carbonyl group in acetone increases its polarity compared to the ester group in ethyl acetate. Additionally, acetone can participate in hydrogen bonding with other molecules, further increasing its polarity.

Is propanol more polar than acetone?
Ethanol is more polar than acetone because in acetone the carbon that the O is bonded to is sp2 hybridized where as the carbon that the O is bonded to in ethanol is sp3 hybridized. Since the sp2 carbon is more polar than the sp3 carbon, acetone has a lower dielectric constant. Hope this helps.
Is methanol more polar than acetone?
Yes, methanol is more polar than acetone because it has a higher dipole moment and stronger hydrogen bonding capabilities due to its hydroxyl group. Acetone is a less polar solvent compared to methanol.
Differentiation polarity of acetone and ethanol?
Acetone is a polar molecule due to the presence of a carbonyl group, making it capable of hydrogen bonding. Ethanol is also polar due to the presence of a hydroxyl group, which allows for hydrogen bonding. However, acetone is more polar than ethanol because of the stronger dipole moment of the carbonyl group compared to the hydroxyl group.
Why ethylacetate is more polar than chloroform?
Ethyl acetate is more polar than chloroform because it contains both an ester functional group and an oxygen atom, leading to a higher dipole moment and increased polarity. In contrast, chloroform only contains a single electronegative chlorine atom, making it less polar than ethyl acetate.
Why does acetone evaporates faster than n-hexane?
Acetone evaporates faster than n-hexane because it has weaker intermolecular forces. Acetone molecules are more polar and can form hydrogen bonds, which makes them easier to break apart and evaporate. n-hexane molecules have stronger dispersion forces, requiring more energy to overcome and evaporate.
Is acetone more polar than ethylacetate?
yes
Is propanol more polar than acetone?
Ethanol is more polar than acetone because in acetone the carbon that the O is bonded to is sp2 hybridized where as the carbon that the O is bonded to in ethanol is sp3 hybridized. Since the sp2 carbon is more polar than the sp3 carbon, acetone has a lower dielectric constant. Hope this helps.
Is methanol more polar than acetone?
Yes, methanol is more polar than acetone because it has a higher dipole moment and stronger hydrogen bonding capabilities due to its hydroxyl group. Acetone is a less polar solvent compared to methanol.
Is caffeine more soluble in acetone or methylene chloride?
Caffeine is more soluble in methylene chloride than in acetone. Methylene chloride is a non-polar solvent, while caffeine is a polar compound. Polar compounds like caffeine tend to be more soluble in non-polar solvents like methylene chloride.
Differentiation polarity of acetone and ethanol?
Acetone is a polar molecule due to the presence of a carbonyl group, making it capable of hydrogen bonding. Ethanol is also polar due to the presence of a hydroxyl group, which allows for hydrogen bonding. However, acetone is more polar than ethanol because of the stronger dipole moment of the carbonyl group compared to the hydroxyl group.
Why ethylacetate is more polar than chloroform?
Ethyl acetate is more polar than chloroform because it contains both an ester functional group and an oxygen atom, leading to a higher dipole moment and increased polarity. In contrast, chloroform only contains a single electronegative chlorine atom, making it less polar than ethyl acetate.
Is ethyl acetate more polar than toluene?
Yes, ethyl acetate is more polar than toluene. Ethyl acetate contains a carbonyl group that increases its polarity compared to toluene, which is a nonpolar solvent.
Why does acetone have a lower surface tension than water?
Acetone has a lower surface tension than water because it has weaker intermolecular forces due to its molecular structure. The molecules in acetone are less able to attract each other compared to water molecules, resulting in a lower surface tension.
Is ethanol more volatile than acetone?
Acetone is more volatile than ethanol.
Is ethyl acetate polar?
Yes, ethyl acetate is polar because the molecule has a permanent dipole moment due to the difference in electronegativity between the carbon, hydrogen, and oxygen atoms in the molecule.
Is acetone polar or nonpolar?
Acetone is a polar molecule due to its carbonyl functional group (C=O) which results in unequal sharing of electrons between carbon and oxygen, creating a partial negative charge on the oxygen and a partial positive charge on the carbon.
Why does acetone evaporates faster than n-hexane?
Acetone evaporates faster than n-hexane because it has weaker intermolecular forces. Acetone molecules are more polar and can form hydrogen bonds, which makes them easier to break apart and evaporate. n-hexane molecules have stronger dispersion forces, requiring more energy to overcome and evaporate.
