Cyclopropane is an interesting hydrocarbon. Instead of having three carbons in a row, the three carbons form a ring, as shown in this perspective Figure 2 (see Figure 1.1 and Figure 1.2 for a prior example of this kind of drawing): Figure 1.1 Figure 1.2 Figure 2 Cyclopropane was at one time used as an anesthetic, but its use was discontinued, in part because it is highly inflammable, (a) What is the empirical formula of cyclopropane? How does it differ from that of propane? (b) The three carbon atoms are necessarily in a plane. What do the different wedges mean? (c) What change would you make to the structure shown to illustrate chlorocyclopropane? Are there isomers of chlorocyclopropane?
Solution Step 1 : Cyclopropane is a cycloalkane molecule with the molecular formula C H . It consists of3 6 three carbon atoms linked to each other to form a ring, with each carbon atom bearing two hydrogen atoms.
