- Picric acid is more acidic than benzoic acid because picric acid contains three NO2 groups which is electron withdrawing group.
Which is more acidic picric or benzoic acid?
Since picric acid has 3 -NO 2 groups and an -OH group, the -I effect on benzene is highest. Hence, it has the highest acidity and lowest pKa value. In salicylic acid , there is one -COOH group and an -OH group. In benzoic acid , there is only one -COOH group.Which acid is more acidic than benzoic acid?
Formic acid and oxalic acid are stronger acids than benzoic acid.What is the difference between picric acid and benzoic acid?
The key difference between picric acid and benzoic acid is that picric acid is available as a yellow color powder form, whereas benzoic acid is available as a crystalline solid that is colorless. Moreover, picric acid is odorless, while benzoic acid has a faint, pleasant odor.- Phenol is less acidic than carboxylic acid however presence of three nitro group at ortho and para position makes picric acid even more stronger than formic acid.
