Definition
- Adjective:
- Relating to or containing the carboxyl group: The term "carboxylic" describes a substance or chemical property that is connected to or possesses the carboxyl functional group (-COOH).
Usage
- The adjective "carboxylic" is used almost exclusively in scientific contexts, particularly in organic chemistry and biochemistry. It modifies nouns to specify the presence or nature of the carboxyl group.
- Example: "The reaction forms a carboxylic acid." (Here, "carboxylic" specifies the type of acid being formed.)
- It is not typically used in everyday language.
Examples
- Adjective:
- Fatty acids are long-chain carboxylic acids.
