Question

Critical Thinking Questions: 12. Label one box in Model 4 with the name "dis-1,2-dimethylcyclobutane" and the other with the name "trans-1,2-dimethylcyclobutane." Then add perspective representations into each box. 13. Draw wedge-and-dash and perspective representations of cis- and trans-1,3- dimethylcyclobutane. (Note: that is "1,3-dimethyl, not "1,2-dimethyl.") Do not answer this question Exercises: 1. Indicate if the following pairs of structures are identical, conformers, geometric isomers, constitutional isomers, or not isomers. a. 1,2-dimethylcyclobutane and 1,3-dimethylcyclobutane b. and Y 2 Draw a structure for a molecule not shown in this activity that would belong in Column 2 7 of Model 2 DO NOT ANSWER THIS ONE
