The dipole value of methoxymethane is 1.3 D. Therefore we can say that CH3OCH3 is inherently slightly polar.
CH3OH is a polar molecule because the dipole-dipole moment is not canceled due to its asymmetric shape.
Acetic acid (CH3COOH) is a polar molecule because it contains double-bonded oxygen, which is more electronegative than a carbon atom, so the difference in electronegativity in carbon and oxygen atom creates a dipole moment in the C-O -bond because they induce a positive and negative charge.
The oxygen bonded to carbon tends to attract the bonding electron pair between oxygen and carbon, hence CH3COCH3 is polar.
In summary, CH3OH is a polar and a neutral compound that has tetrahedral geometry and curved and tetrahedral shapes with respect to the oxygen and carbon atoms, respectively. It has three non-polar C-H sigma bonds, one polar C-O sigma bond and one polar O-H sigma bond along with hybridization of sp3.
Methyl alcohol is a polar covalent compound.
For the CH3OCH3 Lewis structure, we have a total of 20 valence electrons.
The answer is Yes.
Because the electronegativity difference there is too small. Overall, CH3CH3 (ethane) is a non-polar compound.
Chemical structure and functional group of acetone:
Acetone, an organic compound, is chemically named CH3COCH3 and can also be referred to as 2-propanone. Acetone is a hydrocarbon derivative, more specifically a ketone in its simplest form due to its particular functional group.
The C-O bonds of methoxymethane (dimethyl ether) (CH3-O-CH3) are polar. The geometry of the molecule is angular, resulting in an overall molecular dipole. Therefore, the molecule will be subject to dipole-dipole and dipole/induced dipole interactions as well as the stronger dispersion forces.
