How did the grouping of structures required in 12 assist in your analysis?c. Determine the effect that adding an oxygen atom to a 7 carbon hydrocarbon has on the number of hydrogen atoms present in the molecule?Explain. How did the grouping of structures required in 12 assist in your analysis?d. How did the grouping of structures required in 12 assist in your analyses in a -> c?14. Devise a general approach for determining the number of rings or multiple **bond**s in any molecule that contains one or more N, O or halogen atomsfrom its molecular formula, without drawing any structures.15. Below are listed four new molecular formulas.C 5 H 9 N C7H 14 O C15H 29 Cl C 9 H 16 NOBrWithout drawing any structures, what can you predict about the number of rings or multiple **bond**s that must be present in molecules with each of thesemolecular formulas? Explain your logic.

Double Bond **Eq**uivalents 516. Use the method developed in 14 to write the molecular formulas of the following structures without counting all of the atoms. Which atoms must becounted? Which ones can be determined from your relationship from 14 above? Explain the logic you used.ONHOCC Cl17. Look back at the process used to reach your method in 14. There were three data organizing steps in these analyses. (Steps 2, 5 & 12) Comment onthe value of each operation as a general problem solving strategy.
