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.
2-butyne
This does not exist as prop means 3, and you cannot have a triple bond on the 3rd carbon to another carbon if it is not there. I'll link 2 methyl 3 butyne as it is hard to explain. However, I'm pretty sure under IUPAC, it should be named 3 methyl 1 butyne at that.
It is liquid at room temperature. Boiling point is ~30°C
What is the molecular formula of 2-Butyne
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.
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
There are two isomers of butyne. Butyne has only four carbon atoms with a triple bond. The triple bond can ONLY be located between the FIRST and SECOND carbon atom or the SECOND and THIRD carbon atoms. (A triple bond between the third and fourth carbon atom is only a reverse of the first and second combination).

It depends upon the structure of C4H6, this formula may be for 1,2-butadiene, 1,3-butadiene, 1-butyne, 2-butyne and cyclobutene. All these compounds may produce chlorine derivative when react with HCl.
Assuming that all the letters are changed to upper case and a chemical bond is implied between the oxygen atom and the carbon atom of each set of three adjacent letters close to it and between the two carbon atoms on each end of the formula, this is the formula of diethyl ether.
Melting points are very different.
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.
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.
