– suffix al- Common names include * formaldehyde for methanal (R = H)* Acetyldehyde for ethanal ( R = CH3)* Propionaldehyde for propanal (R = CH3CH2)
The suffix “al” in organic chemistry is commonly used to denote aldehydes
The suffix “al” in organic chemistry is commonly used to denote aldehydes. Aldehydes are a class of organic compounds that contain a carbonyl group (-C=O) at the end of a carbon chain, with a hydrogen atom (H) attached to the carbonyl carbon.
Three common examples of aldehydes and their corresponding common names are:
1. Methanal: The common name for methanal is formaldehyde. It is represented by the chemical formula HCHO, where R = H. Formaldehyde is a colorless gas with a pungent odor. It is widely used in industry, primarily as a disinfectant, preservative, and in the production of plastics and resins.
2. Ethanal: The common name for ethanal is acetaldehyde. It is represented by the chemical formula CH3CHO, where R = CH3. Acetaldehyde is a volatile liquid with a fruity odor. It is commonly used in the production of chemicals, plastics, and pharmaceuticals. Acetaldehyde is also produced naturally in the body as a byproduct of alcohol metabolism, leading to some of the physiological effects associated with alcohol consumption.
3. Propanal: The common name for propanal is propionaldehyde. It is represented by the chemical formula CH3CH2CHO, where R = CH3CH2. Propionaldehyde is a colorless liquid with a strong, pungent odor. It is primarily used as an intermediate in the production of various chemicals, including pharmaceuticals, fragrances, and insecticides.
In summary, the suffix “al” in organic chemistry denotes aldehydes, which are a class of organic compounds containing a carbonyl group (-C=O) at the end of a carbon chain, with a hydrogen atom (H) attached to the carbonyl carbon. Three common examples of aldehydes and their corresponding common names are formaldehyde (methanal), acetaldehyde (ethanal), and propionaldehyde (propanal).
