1-butyne and 2-butyne are similar to each other in that they are both alkynes, and butyne to be specific. The difference is the placement of the triple bond between carbons. In 1-butyne it is placed on a primary carbon, where in 2-butyne it is placed on the first available secondary carbon.
Butyne is not a molecule. Butyne 1 is classified as an alkaline and is colorless gas. Butyne is very flammable and has a boiling point of 8.08 degrees Celsius.
Butyne has 4 carbons and a triple bond. The triple bond can be between C1 and C2, or C2 and C3 so there are 2 different "forms" or isomers of butyne.
It is an alkene
Lets look at the molecule 2-butyne. H3C-C=C-CH3. Notice this molecule is symmetrical about a triple bond. The C-C triple bond in 2-butyne is IR inactive because of the molecule's overall symmetry. For 1-butyne, you would expect to see a weak peak from 2100-2250 (indicative of a C-C triple bond), but you would not expect to see the same for 2-butyne.
Butyne is an alkyne, but not all alkynes contain butyne as a subunit (to name a trivial example, acetylene does not).
There are 4 carbon atoms in butyne.
Melting points are very different.

What is the molecular formula of 2-Butyne
1-butyne contains a triple bond which can be fugured out from the name butYNE. Number one in the front means that the triple bond is between the first and second carbon atom.
A butyne is either of two isomeric acetylenes containing four carbon atoms and a triple bond.
the difference is where the triple bond occurs. if it occurs between the first and second carbon it is 1-butyne if the triple bond occurs between the second and third carbon it is 2-butyne the difference is where the triple bond occurs. if it occurs between the first and second carbon it is 1-butyne if the triple bond occurs between the second and third carbon it is 2-butyne
