What Are the Isomers for Butyne?

Isomers for butyne include 1-butyne, 2-butyne, 1-methylcyclopropene, 1,2-butadiene, 3-methylcyclopropene, bicyclo[1.1.0]. cyclobutene, 1,3-butadiene and methylenecyclopropane. All of these molecules have four carbon atoms, some with double or triple bonds and six hydrogen atoms in various configurations.

Ethylacetylene is another name for 1-butyne. It's a very flammable but colorless gas. One of its isomers, 2-butyne, is a man-made, volatile liquid.

1-methylcyclopropene is a gas that is related to ethylene. It is used to retard the ripening of plants, including fruits and cut-flowers. This allows them to be shipped long distances without wilting or overripening.

Methylenecyclopropane is a colorless gas. It's used as a reagent, which means that it's a substance used to affect some kind of transformation or chemical reaction on a system.

1,3-butadiene is also a colorless gas with a somewhat pleasant odor. However, it is very reactive and considered a fire hazard. It irritates mucous membranes, including the eyes and respiratory tract and causes symptoms such as nausea, dizziness and hypotension. Long-term effects might include heart disease and cancer, though this isn't conclusive.

1,3-butadiene can be dissolved in alcohol but not in water, has a boiling point of 24 degrees F and a melting point of minus 164 degrees F.
