Is p-nitrobenzoic acid soluble in ether?
One gram dissolves in 2380 mL water, 110 mL alcohol, 12 mL methanol, 150 mL chloroform, 45 mL ether, 20 mL acetone; slightly soluble in benzene, carbon disulfide; insol in petroleum ether.
Is m-nitrobenzoic acid polar?
Here is a table that summerizes the relative polarity of the above molecules….The molecules and their Lewis structures.
| Molecule | Relative Polarity and Comments |
|---|---|
| m-nitrobenzoic acid | somewhat polar –N and O partially cancel each other |
Is 4 nitrobenzoic acid a weak acid?
4-Nitrobenzoic acid is a stronger acid because the nitro group makes the aromatic ring unstable.
Why is nitrobenzoic acid more acidic than benzoic acid?
Both o-nitrobenzoic and p-nitrobenzoic acid are more acidic than benzoic acid due to presence of electron withdrawing group which increases the acidity of acid. o-nitrobenzoic acid is more acidic compared to p-nitrobenzoic acid.
Is 4-nitrobenzoic acid more acidic?
Further, larger the number of electron-withdrawing groups, more is the acidity. Thus, 3,4-dinitrobenzoic acid (III) is more acidic than 4-nitrobenzoic acid (II) and both tare more acidic than benzoic acid (I).
Will benzoic acid react with water?
The primary reason benzoic acid dissolves only slightly in cold water is that, even though the carboxylic acid group is polar, the bulk of the benzoic acid molecule is non-polar (water is polar). It is only the carboxylic group that is polar.
Which is more acidic ortho meta or para nitrobenzoic acid?
The acidity of ortho-nitrobenzoic acid is more as compared with para-nitrobenzoic acid because of the “ortho effect”.
Which is more acidic ortho nitro benzoic acid or para nitrobenzoic acid?
The acidity of ortho-nitrobenzoic acid is more as compared with para-nitrobenzoic acid because of the “ortho effect”. The explanation is relying on the steric inhibition of the resonance of the COOH group.
