A functional isomer of 1-butyne is 1,3-butadiene. Both have the same molecular formula C 4 H 6 but differ in the nature of the functional group.
1-Butyne is a terminal alkyne with a triple bond that connects first and second carbon atoms. 2-Butyne is a non-terminal alkyne with a triple bond that connects second and third carbon atoms.
Both 1-butyne and 2-butyne are hydrocarbons that belong to the group of alkynes. 1-butyne is a terminal alkyne that has a triple bond connecting C1 and C2. It is a colorless gas. 2-butyne is a colorless liquid that has its triple bond connecting C2 and C3 atoms. Hence 2-butyne is a non-terminal alkyne.
Butyne is a compound with the chemical formula of C4H6. We know it has four carbon atoms from the 'but' portion of the name which means four. The 'yne' refers to a triple bond. So somewhere in the compound is a triple bond. Carbon based compounds with a triple bond are called alkynes.
