Acetonitrile is a more polar molecule than methanol because of the triple bond and lone pair on the nitrogen (N) atom in acetonitrile. This makes that end of the molecule highly electronegative, even more so than an oxygen (O) atom containing two lone pairs in methanol.

Methanol is more polar than acetonitrile because it has a higher dipole moment due to the difference in electronegativity between carbon and oxygen in methanol. Additionally, methanol can participate in hydrogen bonding, which further increases its polarity compared to acetonitrile.

∙ 13y agoNo, neither is. In order to be considered a halogenated compound, the material must contain an element that is considered a halogen; either fluorine, chlorine, bromine, or iodine. Neither of these compounds contain any of these elements.

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.
Which is more polar Trifluoroacetic acid or Acetonitrile?
In aqueous buffers, trifluoroacetic acid will be more polar because it will ionize to form trifluoroacetate. Acetonitrile has no acid/base chemistry and will not ionize. Since ions are very, very "polar", trifluoroacetate wins. I guess the answer may depend on the solvent, though. Both acetonitrile and TFA are highly polar, even when not ionized. Witness their complete miscibility with water, e.g. polarity depends on polarising groups/atoms. In trifluroacetic acid polarity is due to electronegativity and resonance which stabilises the anion. in the case of acetonitrile polarity is due to the electronegative difference between carbon and nitrogen.
Is chloroform soluble in acetonitrile?
Yes, chloroform is soluble in acetonitrile. Acetonitrile is a polar solvent, while chloroform is a nonpolar solvent, but they can still mix together and form a homogeneous solution.
Is 3 Tetraphenylcyclopentadienone soluble in methanol?
Tetraphenylcyclopentadienone is not very soluble in methanol due to its non-polar nature and the methanol being more polar. However, small amounts may dissolve due to partial solubility.
Is zinc fluoride soluble in methanol?
Yes, zinc fluoride is soluble in methanol. Zinc fluoride is a polar compound, and methanol is a polar solvent, which allows for the dissolution of zinc fluoride in methanol.
What compound is more polar and soluble in water methane or methanol and why?
Acetonitrile is slightly more polar than methanol. This is due to the presence of the C-N triple bond in acetonitrile (CH3CN).
Which is more polar acetonitrile or methnol?

Why is acetonitrile more polar Why not methanol.O is more electro-ve. my guess is that nitrogen is in the end in the molecule whereas in methanol oxygen has hydrogen on one hand and carbon on another?
In Acetonitrile carbon (EN-value on Pauling's scale is 2.5) of cyanide is attached with Nitrogen(EN-value on Pauling's scale is 3.0), so , Nitrogen atom with combination of carbon, that is more EN than Hydrogen(EN-value on Pauling's scale is 2.1) attached with oxygen atom (EN-value on Pauling's scale is 3.5) in methanol, becomes more Electron withdrawing effect than -OH group in methanol. In this way -CN is more dispersive than that of -OH.
Is chloroform soluble in acetonitrile?
Yes, chloroform is soluble in acetonitrile. Acetonitrile is a polar solvent, while chloroform is a nonpolar solvent, but they can still mix together and form a homogeneous solution.
How do you dissloved polar solvents?
polar solvents dissolved in water most of times ,and methnol,acetonitrile

Yes, zinc fluoride is soluble in methanol. Zinc fluoride is a polar compound, and methanol is a polar solvent, which allows for the dissolution of zinc fluoride in methanol.
What are polar and non-polar liquids?
A polar liquid is a liquid that does not have any/much of a hydrocarbon chain and has mainly OH, NH or even C=O or C=-N groups. As you increase the carbon chain, you become less polar. Polar solvents include water, dimethylformamide, ethanol, methanol, acetonitrile to name a few. Non polar solvents include pentane, hexane, toluene, heptane to name a few.
Is methanol more soluable than methane?
Yes, methanol is CH3OH and methane is CH4. Methanol is polar (because of the O-H bond) and methane is non-polar (because it is a hydrocarbon.) Water (which is polar) will dissolve other polar things, but not non-polar things.
What would happen to the isolation process if you use a more polar solvent such as methatnol inteasd of dietyl ether?
Most of the organic compounds are not sufficiently polar and are insoluble in polar solvent like methanol so only polar fractions may be separated by using methanol.
