A student is a writing a research report on how plastic is produced, and finds out that certain types of plastic are made from a chemical called 1-butene (C₄H₈ ). The ball-and-stick model of 1-butene is shown. The student decides to build another model. Which of the following ball-and-stick models has the same atomic composition as, but different properties from, 1-butene?
