Exercise 9 in Part B asks you to draw all possible isomers (constitutional isomers and configurational stereoisomers) with molecular formula C6H12. A good way to go about answering such a problem is to start by drawing all possible six-carbon backbones that can accommodate either a ring or a double bond. Then for each unique backbone without a ring, draw all possible ways to accommodate a double bond. For example, a six-carbon straight chain can accommodate a double bond in the five ways shown below.

(Reference Exercise 9)

Draw the one constitutional isomer that is missing from column 1 of Model 7
