GCSE Chemistry - Esters #59

Esters are compounds with a COO functional group, known for their pleasant, fruity smells and volatility. They are used in perfumes and food flavorings. Esters are synthesized from carboxylic acids and alcohols, with ethyl ethanoate as an example, requiring an acid catalyst like concentrated sulphuric acid. The reaction produces water as a byproduct. The COO group, also called an ester link, connects the carboxylic acid and alcohol in the molecule.

What is the key feature of esters that distinguishes them from other compounds?

Describe the distinctive property of esters related to their smell.

What are the two main components needed to create an ester?

Explain the role of the acid catalyst in the formation of esters.

What is formed as a byproduct during the reaction to create an ester?
