Question Bank
What are the key safety considerations when working with carboxylic acids and esters?
Carboxylic acids and esters can be corrosive and irritating to the skin and eyes. Proper personal protective equipment, such as gloves, goggles, and a lab coat, should be worn at all times. Additionally, these compounds are flammable, so open flames and heat sources should be avoided.
How can I identify carboxylic acids and esters in a reaction mixture?
Carboxylic acids can be identified by their characteristic odor and their ability to react with bases to form salts. Esters have a fruity or floral odor and can be hydrolyzed to form carboxylic acids and alcohols.
What are some common applications of carboxylic acids and esters?
Carboxylic acids are used in the production of plastics, dyes, and pharmaceuticals. Esters are used as solvents, flavors, and fragrances.
