Question:

Carboxylic acid and ester can form isomers. What are the conditions?

Carboxylic acid and ester can form isomers. What are the conditions?

Answer:

The general formula for the carboxylic acid is RCOOH, and the general formula for the carboxylic acid ester is R? COOR? (R? May be a hydrogen atom). If the total number of carbon atoms in the R group in the carboxylic acid is the same as the total number of carbon atoms of the two R groups (R + R?) in the carboxylic acid ester and the total number of R atoms in the carboxylic acid is higher than that of the carboxyl groups R & lt; 1 & gt; R & lt; 2 & gt;), both of which constitute isomers, such as acetic acid and methyl formate, butyric acid and ethyl acetate, phenylacetic acid and methyl benzoate are all isomers.
