Exploring the Chemistry and Applications of Aldehydes in Science and Industry

Common Names of Aldehydes

– An aldehyde has a terminal functional group due to the one hydrogen- Ketone has two alkyl groups so it’s never a terminal group.

Aldehydes are a class of organic compounds that contain a carbonyl group (-CHO) attached to a carbon atom. Some of the common names of aldehydes are:

1. Formaldehyde: This is the simplest aldehyde, also known as methanal. It is a highly reactive gas and is commonly used as a disinfectant, preservative and in the production of plastics.

2. Acetaldehyde: This is the second simplest aldehyde and is also known as ethanal. It is a colorless liquid with a pungent smell. It is mainly used in the production of other chemicals and as a flavoring agent in food.

3. Propionaldehyde: This is an aldehyde with the formula C3H6O. It has a fruity odor and is used in the production of herbicides and pharmaceuticals.

4. Butyraldehyde: This is an aldehyde with the formula C4H8O. It has a strong, unpleasant odor and is used in the production of plastics, rubber chemicals and synthetic perfumes.

5. Benzaldehyde: This is an aromatic aldehyde with the formula C7H6O. It has a sweet almond-like odor and is used in the production of dyes, perfumes, and flavorings.

6. Vanillin: Although vanillin is not an aldehyde, it has a similar structure and is often used as a flavoring agent. It is derived from the pod of the vanilla orchid and has a sweet, vanilla-like odor.
