Practice Problem 9.2 Draw a tetrahedral representation of (/ ) 2 chlorobutane. 

Although informative, the structural formula is time-consuming to draw. Therefore, chemists have devised ways to simplify the representation. Figure 16.3(b) is an abbreviated version, and the structure shown in Figure 16.3(c) is called the skeletal structure in which all the C and H letters are omitted. A carbon atom is assumed to be at each intersection of two lines (bond) and at the end of each line. Because every C atom forms four bonds, we can always deduce the number of H atoms bonded to any C atom. The element symbols for substituent atoms in the skeletal structure are always shown explicitly, such as in l-bromo-3-chlorobutane [C4H8BrCl] ...
