Question

For each problem, you must determine the exact molecular structure. All HNMR signals must be labeled with their H assignments.

The major IR absorption bands must be labeled with their corresponding assignment (ie, C=O).

                                    

                                        Can you guys also expain in detail for me how to solve these problems because i don't understand it very well?                                     

                                                                             Thanks

Explanation / Answer

This is chlorotoluene. From the formula we can see that there is a benzene ring with 2 substituents, 1 CH3 and 1 Cl. According to HNMR data, we can make out whether it is o, m or p. Finally the IR data can be calculated corresponding to known values
