These compounds are composed of a triple bond per molecule. Geometric isomers are isomers in which the order of atom bonding is the same but the arrangement of atoms in space is different. 2-Butyne is the most stable butyne isomer. The third carbon does not count as another isomer because if we start counting from the other end the triple bond is actually located at the second carbon.
