Propanone, also known as acetone, has a significant overall dipole moment due to its molecular structure. The carbonyl group (C=O) in propanone is highly polar, with a strong electronegativity difference between carbon and oxygen, resulting in a partial negative charge on the oxygen and a partial positive charge on the carbon. Additionally, the presence of two methyl groups (CH3) on either side of the carbonyl group does not cancel out the dipole moment, leading to a net dipole in the molecule. This polarity contributes to its solubility in polar solvents and its ability to engage in dipole-dipole interactions.

Why does this molecule CH3COCH3 has a largest overall dipole?
The molecule CH3COCH3, known as acetone, exhibits a significant overall dipole due to the presence of a carbonyl group (C=O) that creates a strong polar bond. The oxygen atom is more electronegative than carbon, resulting in a partial negative charge on the oxygen and a partial positive charge on the adjacent carbon atoms. This polar character, combined with the asymmetrical shape of the molecule, leads to a net dipole moment, making acetone a polar solvent with a larger overall dipole compared to nonpolar molecules.
What ia trivial name of propanone?
The trivial name for propanone is acetone.
What temperature does propanone freeze?
The freezing point of propanone is -94,7 oC.
Does NOCl dipole forces?
Yes, NOCl exhibits dipole-dipole forces because the molecule has a net dipole moment due to the unequal sharing of electrons between nitrogen, oxygen, and chlorine atoms. This results in an overall polarity, causing molecules to attract each other through dipole-dipole interactions.
Does propanol have dipole dipole forces?
Yes, propanol (specifically, 1-propanol) has dipole-dipole forces. This is due to the presence of a hydroxyl (-OH) group, which creates a polar bond between the oxygen and hydrogen atoms. The molecule's overall polarity results in dipole-dipole interactions between the molecules, contributing to its physical properties, such as its boiling point.
Why does propanone has a higher boiling point than ethoxyethane?
Ethoxyethane is heavier than propanone and that will surely make a difference. The carbon-oxygen bond in ethers is less polarized than that in aldehydes and ketones. This is because the oxygen in ethers is attached to two electron pushing alkyl groups which account for the oxygen atom's electronegativity. Thus, dipole-dipole interactions are weaker in ethers giving them a lower boiling point than the corresponding aldehyde or ketone.
How does paracetamol dissolve in propanone?
Paracetamol dissolves in propanone due to the polar nature of both substances. Paracetamol contains a hydroxyl group (-OH) and an amide group, which can form hydrogen bonds with the polar carbonyl group of propanone. This interaction facilitates the solvation of paracetamol molecules in the propanone solvent, allowing it to dissolve effectively. The overall process is driven by the principles of solubility, where "like dissolves like."
Why does this molecule CH3COCH3 has a largest overall dipole?

This polar character, combined with the asymmetrical shape of the molecule, leads to a net dipole moment, making acetone a polar solvent with a larger overall dipole compared to nonpolar molecules.
Which pair of bonded atoms has the largest dipole moment?
The pair of bonded atoms with the largest dipole moment is the one with the largest difference in electronegativity. This means that atoms with very different electronegativities, such as a bond between hydrogen and fluorine, will have a larger dipole moment compared to bonds with smaller electronegativity differences.
What ia trivial name of propanone?
The trivial name for propanone is acetone.
Is propanone same as acetone?
Yes, propanone is acetone for all practical purposes.
Why does propanone has higher vapour pressure than ethanol at room temperature?
The intermolecular forces (IMFs) that attract propane molecules to eachother is far weaker than the IMFs of ethanol molecules. Consequently there is less of an energy barrier for a propane molecule to evaporate. IMFs of propare are limited to the london dispersion forces, which are the weakest IMFs IMFs of ethanol are the london dispersion forces as well as the dipole-dipole interaction (- charge on oxygen and positive on hydrogen) and hydrogen bonding (very strong IMF)
How does symmetry affect the dipole moment of a molecule?
Symmetry affects the dipole moment of a molecule by determining whether the individual dipole moments of its bonds cancel out or add up. A molecule with overall symmetry may have a zero dipole moment due to opposing dipoles, while asymmetric molecules will have a non-zero dipole moment. Symmetry can influence the overall polarity and reactivity of the molecule.
What temperature does propanone freeze?
The freezing point of propanone is -94,7 oC.
Does NOCl dipole forces?
Yes, NOCl exhibits dipole-dipole forces because the molecule has a net dipole moment due to the unequal sharing of electrons between nitrogen, oxygen, and chlorine atoms. This results in an overall polarity, causing molecules to attract each other through dipole-dipole interactions.
Does pcl4f2 have a dipole moment?
Yes, PCl4F2 has a dipole moment because the molecule is asymmetrical with the fluorine atoms pulling electron density towards their side and creating an overall dipole moment.
What molecule has an overall dipole moment?
All polar molecules have a permanent dipole moment, but London dispersion forces in non-polar molecules can cause temporary dipole moments as well.
