Is 4 methoxy benzoic acid or benzoic acid more acidic?
-Since electron-donating groups decrease the acidic strength, $4 – $ methoxy benzoic acid is a weaker acid than benzoic acid.
Which is more acidic Ortho hydroxybenzoic or para Hydroxybenzoic Why?
Ortho hydroxybenzoic acid is more acidic than para hydroxybenzoic acid because, the lower the pka value increases the acidity of that compound and higher the pka value decreases the acidity of that compound.
Which is more acidic meta hydroxybenzoic acid or para hydroxybenzoic acid?
So, meta-hydroxybenzoic acid is more acidic than para-hydroxybenzoic acid.
Why o hydroxybenzoic acid is stronger than p-hydroxybenzoic acid?
o-hydroxybenzoic acid is more acidic than p-hydroxybenzoic acid because its conjugate base is more stable. In o-hydroxybenzoic acid, the hydroxyl group is close enough to the carboxylic acid that the deprotonated oxygen can hydrogen bond with the hydroxyl group.
How do you synthesize Acetoxybenzoic acid?
Procedure Place 2 g. of dry 4-hydroxybenzoic acid and 3 g (3 mL) of acetic anhydride (Note 1) in a small conical flask, add 1 drop of concentrated sulfuric acid, and rotate the flask in order to secure thorough mixing. Warm on a water bath to about 50-60ºC, with stirring, for about 15 minutes.
Which of the following is used as antipyretic Acetoxybenzoic acid?
Aspirin
2-acetoxybenzoic acid is IUPAC name of Aspirin. Aspirin acts as antipyretic, which is used to reduce body temperature.
Which is more acidic benzoic acid or o hydroxybenzoic acid?
o-hydroxybenzoic acid is less/more acidic than p-hydroxy benzoic acid.
Which is more acidic meta methyl benzoic acid or para methyl benzoic acid?
The methyl group at ortho & para-position(4-position) destabilises Negative charge of corresponding Carboxylate ion both +I (Inductive ERG)) as well as by +H (hyperconjugation). Hence m-isomer is more acidic than para-isomer.
