2-Butyne (dimethylacetylene, crotonylene or but-2-yne) is an alkyne with chemical formula CH 3 C≡CCH 3. Produced artificially, it is a colorless, volatile, pungent liquid at standard temperature and pressure.

Because each Carbon atom can only have four bonds, we'll remove H atoms. This gives us the correct structure for 2-Butyne. You will sometimes see it written as CH3C≡CCH3.
