How many total of carbon atoms are in 3-chloro-3-isopropyl-2-methyldecane (Note: No need to write structure formula)  

Company X is a company located in San Antonio, TX and it has 250 employees. In Spring 2026, the company conducted a survey with employees and found that employees were really interested in participating in a work-based physical activity program. Thus, Company X recently hired a Health Education Specialist and Program Coordinator to create a new physical activity program for its employees. Which level of the Socio-Ecological Model is being described through the creation of the physical activity program being carried out at Company X?

Match the structure with the appropriate H NMR spectra. KEEP IN MIND THE CHOICE ARE THE SPECTRA NOT THE MOLECULES. Spectra A: If image does not load click here Spectra B: If image does not load click here Spectra C: If image does not load click here

Question 8 Provided are spectra for a compound with molecular formula C9H12O Part A) Determine the degrees of unsaturation for C9H12O  (3 pts) The formula is DU = (2C+2-H-X+N)/2. Part B) Using the IR spectra complete the following table. (6 pts) IR signal (cm-1) Corresponding Bond Functional Group  3336 3063 1601 Part B) Draw the structure (6 pts) and clearly indicate which hydrogens correspond to which signals in the HNMR spectrum ONLY.  The signals are already labeled A-E on the HNMR spectrum.  Match the hydrogen labeling (HA, HB, etc.) on your drawn structure to the signal labeling provided. Do NOT make up your own labels and match what is provided. (10 pts) H NMR: If image does not load click here IR spectra: If image does not load click here C NMR (note this is only to aid you for the problem, there’s no question regarding the C NMR): If image does not load click here
