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.
- The carboxylic group is highly polar and influences the molecule's solubility.
- This enzyme catalyzes the oxidation of aldehydes to carboxylic derivatives.
Advanced Usage
- "Carboxylic acid": This is the most common compound term. It refers to an organic acid containing a carboxyl group.
- Acetic acid (vinegar) is a simple carboxylic acid.
- "Carboxylic derivative": Refers to a compound that can be formally derived from a carboxylic acid by replacing the hydroxyl group (-OH) with another atom or group.
- Esters and amides are important carboxylic derivatives.
Variants and Related Words
- Carboxyl (noun): The univalent radical -COOH, which is the functional group defining carboxylic acids and their derivatives.
- The carboxyl group consists of a carbonyl and a hydroxyl.
- Carboxylate (verb/noun):
- (Verb) To introduce a carboxyl group into a compound or to convert into a carboxylic acid salt.
- The base will carboxylate the intermediate.
- (Noun) A salt or ester of a carboxylic acid.
- Sodium acetate is a common carboxylate.
Synonyms
- -oic acid (suffix): In systematic chemical nomenclature, the suffix "-oic acid" in a compound name (e.g., "hexanoic acid") implies it is a carboxylic acid. "Carboxylic" is the adjectival form describing this class.
- Containing -COOH: A descriptive phrase rather than a direct synonym.
Adjective
- relating to or containing the carboxyl group or carboxyl radical
