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.

Which is more polar methanol or acetonitrile and why?
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.
What is more acidic acetic acid or formic acid or prop ionic acid?
Formic acid is more acidic because formic acid is a smaller molecule as compare to acetic acid so polarity is working in small area and O-H bond is more polar HCOOH, in acetic acid the additional CH3- group is an electrons donor group so O-H bond is little bit stronger and less polar so it is weaker acid.
Is ethanoic acid an electrolyte?
Ethanoic acid is polar because of the way the atoms are arranged within the molecule. They have one side that is more negative then the other.
Why melting point of ethanoic acid is higher than propanoic acid?
Ethanoic acid is more polar than propanoic acid, as it contains fewer carbon-carbon and carbon-hydrogen bonds.
Polyatomic ions are usually?
Ions are charged by definition: they are atoms or molecules that have either lost or got one or more electrons so to have a positive or negative charge. Examples are Trifluoromethan ion CF3- Trifluoroacetic acid ion CF3COO- Nitrogen ion NH2-
Which is more polar acetonitrile or methnol?
Which is more polar acetonitrile or methnol?
Stronger acid trichloracetic acid or trifloracetic acid?
Trifluoroacetic acid by a bit as fluorine is more electronegative than chlorine.
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 methanol or acetonitrile and why?
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.
Which one is more polar naphthalene or butyric acid?
butyric acid is more polar
Among acid and ester which is more polar?
an acid is more polar than an ester
What is more polar methyl salicylate or salicylic acid?
salicylic acid (an acid) is more polar than methyl salicylate (an ester)
What is more polar aspirin or salicylic acid?
Salicylic acid i would think Look at both their structures; salicylic acid has more polar -OH bonds
Is phenyl acetate or butyric acid more polar?
butyric acid
Which is more polar cholesterol or cholesteryl acetate?
As you can see here this is the equation of acetic and stearic acid.it shows how they are different from each other. This is because acetic acid reacts much more exp[losively with water.
What is more acidic acetic acid or formic acid or prop ionic acid?
Formic acid is more acidic because formic acid is a smaller molecule as compare to acetic acid so polarity is working in small area and O-H bond is more polar HCOOH, in acetic acid the additional CH3- group is an electrons donor group so O-H bond is little bit stronger and less polar so it is weaker acid.
Is ethyl acetate polar?
Acetic acid is polar because it is asymmetrical meaning that dipole moment does not get cancel.
