As shown in the figure below, note that the orientation of groups on the first and third carbons are different but the second one remains the same so they are not the same molecule. The four circles indicate the four unique groups attached to the central carbon atom, which is chiral. The simplest alkyne is acetylene, CH. The prefix but- confirms that there are 4 carbon atoms in the molecule. Here, one pi bond of the triple bond is lost, and two hydrogen atoms are attached to the two vinyl carbon atoms (vinyl carbon = carbon atoms that participate in the double bond).
