The two carbon atoms are linked by a strong triple bond, and each carbon''s remaining single bond attaches to a hydrogen atom. However, if tempted with two more hydrogen atoms, the carbons will gladly lessen their grip on each other and change their triple bond to a double one, so that each atom can take on another hydrogen, creating ethylene, C 2 H 4 , which is used in the manufacture of plastics.
