3-hydroxybutanoic acid is a carboxylic acid with a hydroxyl group attached to the third carbon of a four-carbon chain. It is an important compound in the context of naming alcohols and phenols, as it demonstrates the principles of how alcohols are named based on the position of the hydroxyl group.
congrats on reading the definition of 3-hydroxybutanoic acid. now let's actually learn it.
The position of the hydroxyl group in 3-hydroxybutanoic acid is indicated by the number '3', which specifies that the hydroxyl group is attached to the third carbon of the four-carbon chain.
Carboxylic acids are named by identifying the parent chain and adding the suffix '-oic acid' to indicate the presence of the carboxyl group.
The 'butanoic' part of the name refers to the four-carbon (butane) parent chain, and the 'hydroxy' prefix indicates the presence of the hydroxyl group.
The naming of alcohols and phenols follows similar principles, where the position of the hydroxyl group is specified by a number preceding the parent chain name.
Understanding the naming conventions for 3-hydroxybutanoic acid is crucial for correctly identifying and differentiating various alcohols and phenols in organic chemistry.
