Ester Flashcards
What is an ester
Organic compounds formed by the reaction between an alcohol and a carboxylic acid, creating a distinctive ester functional group (-COO-).
Structure of ester
Represented as RCOOR’, where R and R’ are alkyl or aryl groups.
Synthesis of esters
Made through esterification or transesterification reactions, often catalyzed by acids or bases.
Use of Esters
Uses: Found in lipids, essential oils, and plastics. Used in food, fragrance, and pharmaceutical industries.
Reactions what reactions can esters undergo
Reactions: Can undergo hydrolysis to form carboxylic acids and alcohols, or saponification to form carboxylate salts and alcohols.
How are esters named
Follows IUPAC rules, using the alcohol part as the alkyl group and the acid part as the alkylate. Eg ethyl butanoate
The alcohol part (ethyl) comes from the alcohol used in the synthesis, which is ethanol.The acid part (butanoate) comes from the carboxylic acid used, which is butanoic acid.
Stereoisomerism
Stereoisomerism: Can exhibit stereoisomerism if chiral centers are present, resulting in enantiomers with different biological activities.
