– suffix al- Common names include * formaldehyde for methanal (R = H)* Acetyldehyde for ethanal ( R = CH3)* Propionaldehyde for propanal (R = CH3CH2)
Carbonyl group
The suffix “al-” is added to the end of the name of a parent hydrocarbon when one of the hydrogen atoms in the hydrocarbon is replaced with a functional group called an aldehyde group (-CHO). The aldehyde group consists of a carbon atom that is double-bonded to oxygen and single-bonded to hydrogen.
Some common examples of aldehydes include:
1. Formaldehyde, also known as methanal (CH2O): It is a colorless gas with a pungent odor commonly used as a disinfectant and preservative. It is also used in the production of resins, plastics, and textiles.
2. Acetaldehyde, also known as ethanal (CH3CHO): It is a colorless liquid with a pungent odor commonly used as a flavoring agent in foods, as a solvent, and in the production of perfumes and dyes.
3. Propionaldehyde, also known as propanal (CH3CH2CHO): It is a colorless liquid with a pungent odor commonly used as a solvent, in the production of resins and plastics, and as a flavoring agent in foods.
In summary, the suffix “al-” is added to the end of the parent hydrocarbon name to indicate the presence of an aldehyde functional group (-CHO) in the molecule.
