Salicylic Acid – C7H6O3 Salicylic Acid is a type of beta hydroxy acid (BHA) and phenolic acid with a chemical formula C7H6O3. It is a crystalline organic carboxylic acid with keratolytic, bacteriostatic and fungicidal properties.
Which is more acid para hydroxybenzoic acid?
So, meta-hydroxybenzoic acid is more acidic than para-hydroxybenzoic acid. Note: The acid-weakening effect of the electron-donating group and acid-strengthening effect of the electron-withdrawing group is more pronounced at the para than at meta position of the benzoic acid.
What is the correct order of acidity?
So, the correct order of acidity will be: HC≡CH>H3C−C≡CH>H2C=CH2>H3C−CH3. Q3.
Why salicylic acid is stronger acid than p hydroxybenzoic acid?
In salicylic acid, the major effect is hydrogen bonding by the phenolic OH group to the carboxyl group. In the structures below, the hydrogen bond in salicylic acid is shown by a dotted line.
Where can I find p-hydroxybenzoic acid glucoside?
p -Hydroxybenzoic acid glucoside can be found in mycorrhizal and non-mycorrhizal roots of Norway spruces (Picea abies). Violdelphin is an anthocyanin, a type of plant pigments, found in blue flowers and incorporating two p -hydroxybenzoic acid residues, one rutinoside and two glucosides associated with a delphinidin.
How is p-hydroxybenzoic acid dissolved in acetic acid?
p-Hydroxybenzoic acid (55.2 g, 0.4 mole) is dissolved in 175 ml acetic acid and placed in the Parr apparatus. Rhodium on alumina (4 g of 5% catalyst) is added, and the system is briefly evacuated. Hydrogen is introduced to a pressure of 50 psi and shaking is commenced. The absorption of 3 equivalents of hydrogen requires up to 3 days.

What kind of liquid is 4 hydroxybenzoic acid?
4-Hydroxybenzoic acid, or p-hydroxybenzoic acid, is a phenolic derivative of benzoic acid. It a white crystalline solid that is slightly soluble in water and chloroform, but well soluble in alcohols, ether, and acetone.
