What are the acidic hydrogens in salicylic acid?
The OH group bonding with the carbonyl group has a pKa around 5, and the OH group connected ortho of the carbonyl group has a pKa around 10. Added correction: Salicylic acid is a monoprotic, not a diprotic acid in water. From wikipedia table value: pKa 2.97
Salicylic acid formula?
CH2=C=C=C=CH-CH-C=O | \ OH OH CH2=C=C=C=CH-CH-C=O | \ OH OH CH2=C=C=C=CH-CH-C=O | \ OH OH
What elements are in salicylic acid?
Salicylic acid contains carbon, hydrogen, and oxygen.
Why Salysilic acid is stronger than benzoic acid?
In salicylic acid the hydrogen atom in OH group have a tendency to form hydrogen bonding with oxygen atom in the COO - group thus leaving the H+ ion freely available. In case of ortho methoxy benzoic acid, the possibility of hydrogen bonding is avoided by the presence of strong -CH3 group. Hence salicylic acid is stronger than ortho methoxy benzoic acid.
Why is salicylic acid more acidic than acetylsalicylic acid?
Salicylic acid dissociates in water to form a carboxylic acid group, making it more acidic compared to acetylsalicylic acid which has an ester group that is less acidic. The presence of the -OH group in salicylic acid contributes to its higher acidity compared to the -OR group in acetylsalicylic acid.

How does the structure of salicylic acid differ from that of benzoic acid?
Salicylic acid has a hydroxyl group (-OH) attached to the benzene ring, while benzoic acid has a carboxylic acid group (-COOH) attached to the benzene ring. This difference results in salicylic acid being a phenol derivative and having different chemical properties compared to benzoic acid.
What is the mechanism of the salicylic acid and acetic anhydride reaction?
The reaction between salicylic acid and acetic anhydride involves the substitution of a hydroxyl group in salicylic acid with an acetyl group from acetic anhydride. This reaction is catalyzed by an acid, typically sulfuric acid, and results in the formation of aspirin and acetic acid as byproducts.
What is the equation for the reaction of salicylic acid with acetyl chloride?
EsterificationSince the salicylic acid is acid, so it will be reacting with ethanol to form ester The two-part name of an ester: the name of the hyrocarbon group from the alcohol comes first, then the name of the carboxylate group derived from the acid name by replacing "-ic" with "-ate"Therefore the name will be ethyl salicylate C9H10O4 (google it to get the image)
Why hydrogen of COOH group is removed in preparation of methy salicylate from salicylic acid in the presence of sulphuric acid?
why hydrogen of COOH group is removed in the preparation of methyl salicylate from salicylic acid in the presence of sulphuric acid
Simple explanation on how salicylic acid acetyl is made?
Salicylic acid acetyl is made by reacting salicylic acid with acetic anhydride in the presence of an acid catalyst, such as sulfuric acid, to form acetylsalicylic acid. This reaction causes the hydroxyl group (-OH) of salicylic acid to be acetylated, resulting in acetylsalicylic acid, commonly known as aspirin.
What is more polar aspirin or salicylic acid?
Salicylic acid is more polar than aspirin because it has a higher solubility in water due to the presence of a hydroxyl group that enhances its polarity. Aspirin, on the other hand, has an ester functional group, which reduces its overall polarity compared to salicylic acid.
What is decarboxylation of salicylic acid?
Decarboxylation of salicylic acid is a chemical reaction in which carboxylic acid group (-COOH) is removed from salicylic acid, resulting in the formation of phenol. This reaction is often used in organic chemistry to convert salicylic acid into phenol, which has various industrial and pharmaceutical applications.
