Which is more acidic M-toluic acid or p toluic acid?
Note: The acidic strength of m-toluic acid is more than p-toluic acid but less than benzoic acid, actually o-toluic acid also should have less acidic strength than benzoic acid due to presence of the electron withdrawing group.
Is M-toluic acid a base?
m-Toluic acid is a carboxylic acid. Carboxylic acids donate hydrogen ions if a base is present to accept them. They react in this way with all bases, both organic (for example, the amines) and inorganic.

Which toluic acid is most acidic?
Option C is o-hydroxybenzoic acid where hydrogen is attached with oxygen of the hydroxide group, but the hydroxide group is present at the ortho position. Ortho substituted benzoic acids are always most acidic due to ortho effect.
Which toluic acid is more acidic?
It is this stabilization provided by the methyl group that makes o-toluic acid a stronger acid (pKa=3.91) than benzoic acid (pKa=4.19).
What is the density of M toluic acid?
1.05 g/cm³ m-Toluic acid/Density
Is P toluic acid polar or nonpolar?
In p-toluic acid, it contains double-bonded oxygen and a single bonded one but it also contains a methyl group that is of almost the same electro-negativity as C in benzene. So, p-toluic acid is more polar than benzophenone. Therefore, p-toluic acid is the most polar followed by benzophenone and benzil.
What is the molecular weight of M toluic acid?
136.15 g/mol m-Toluic acid/Molar mass
Why o Fluorophenol is weakest acid than P or M?
O-fluorophenol is more acidic than p-fluorophenol. This is because fluorine is more electronegative than oxygen and when both the conjugate bases are formed the negative charge on oxygen is more stabilised by ortho fluorine than by para fluorine due to lesser distance and hence greater inductive effect.
What is the chemical name of m-toluic acid?
m-Toluic acid, ( IUPAC: 3-methylbenzoic acid ), is an aromatic carboxylic acid, with formula (CH 3 )C 6 H 4 (COOH). It is an isomer of p-toluic acid and o-toluic acid . It serves, among other purposes, as a precursor to DEET ( N, N -diethyl- m -toluamide), the well-known insect repellent:
