– suffix al- Common names include * formaldehyde for methanal (R = H)* Acetyldehyde for ethanal ( R = CH3)* Propionaldehyde for propanal (R = CH3CH2)
The suffix “al” is commonly used in the names of aldehydes, which are a class of organic compounds
The suffix “al” is commonly used in the names of aldehydes, which are a class of organic compounds. Aldehydes are characterized by the presence of a carbonyl group (C=O) at the end of a carbon chain. The “al” suffix indicates that the compound is an aldehyde.
Some common examples of aldehydes include:
1. Formaldehyde: The systematic name for formaldehyde is methanal (CH2O). It is the simplest aldehyde, where the carbonyl group is attached to a hydrogen atom. Formaldehyde is a colorless gas with a strong odor and is highly reactive. It is widely used in industrial processes and as a preservative.
2. Acetaldehyde: The systematic name for acetaldehyde is ethanal (CH3CHO). It has an ethyl group (CH3) attached to the carbonyl carbon. Acetaldehyde is a colorless liquid with a pungent odor and is formed during the metabolism of alcohol in the human body. It is also used as a chemical intermediate in various industries.
3. Propionaldehyde: The systematic name for propionaldehyde is propanal (CH3CH2CHO). It has a propyl group (CH3CH2) attached to the carbonyl carbon. Propionaldehyde is a colorless liquid with a fruity odor and is primarily used as a chemical intermediate and in the production of various chemicals.
The “al” suffix in these names helps to identify these compounds as aldehydes. It is important to note that the presence of the carbonyl group gives aldehydes distinct chemical properties and reactivity compared to other organic compounds.
