Dimethyl acetylene is also commonly known as 2-butyne or crotonylene. These names refer to the same chemical compound, a simple alkyne.
Understanding Dimethyl Acetylene
Dimethyl acetylene is a hydrocarbon with a triple bond, belonging to the alkyne family. Its name reflects its structure: "dimethyl" indicates two methyl groups, and "acetylene" refers to the triple bond, similar to the simplest alkyne, acetylene (ethyne).
Alternative Names and Identifiers
The compound is recognized by several names depending on the naming convention used.
| Category | Name |
|---|---|
| Preferred IUPAC Name | But-2-yne |
| Other Common Name | Crotonylene |
| CAS Number | 503-17-3 |
The Preferred IUPAC name, But-2-yne, is derived from the International Union of Pure and Applied Chemistry (IUPAC) nomenclature rules, which provide a systematic way to name chemical compounds. The "but-" prefix indicates four carbon atoms, "-yn-" denotes a triple bond, and "-2-" specifies that the triple bond is located between the second and third carbon atoms in the chain.
Crotonylene is another common, non-systematic name for this compound, often used in older chemical literature or specific industrial contexts.
