Question

what are carboxylic acid? How are they are converted into ester and acetic anhydride
​

Answer 1

Answer:

H2CO3....

Explanation:

Anhydrides are commonly formed when a carboxylic acid reacts with an acid chloride in the presence of a base. The carboxylate anion's negatively charged oxygen attacks the considerably electrophilic acyl chloride's carbonyl carbon. As a result, a tetrahedral intermediate formed.

When a carboxylic acid is treated with an alcohol and an acid catalyst, an ester is formed (along with water). This reaction is called the Fischer esterification. Notes: The reaction is actually an equilibrium.

Answer 2

Answer:

Anhydrides are commonly formed when a carboxylic acid reacts with an acid chloride in the presence of a base. ... The carboxylate anion's negatively charged oxygen attacks the considerably electrophilic acyl chloride's carbonyl carbon. As a result, a tetrahedral intermediate (2) is formed.
