ORGANIC CHEMISTRY PLEASE EXPLAIN, SEE PHOTO: Predict the structure for this unknown. Please provide relevant information regarding each peak and the rationale for how you came to identify each structure. Label any and all peaks. Show all work.

These are IR spectra images that were taken in our lab (first is benzoic acid). Explain the IR peaks corresponding to the functional groups for both products.

Answer no. 88-90

Knowing the properties of organic molecules, students will now design experimental set-ups that will maximize the yield and purity of the target organic molecule. The students must prove that their choice of materials is available for purchase by providing a CAS number or a catalogue from a supplier (example: Sigma Aldrich). Also, included in this part is the discussion of the Chemistry behind the synthesis as well as safe laboratory techniques and practices to synthetic design.

1. One of the keys to organic chemistry is pattern recognition. The following functional groups are not ones we've covered. Based solely which groups you think they resemble, predict whether they are ortho-para or meta directors. d. e. NMe NMe2 f. Given your answers, what structural or electronic features predict whether a functional group will direct ortho-para or meta?

Please examine both of these graphs (Infrared Spectroscopy, and Mass spectroscopy) and determine the bonds, structure, molecular formula and IHD of the unknown organic compound. Please also give reasoning as to why, an explanation would be great. Thank you very much.

Give detailed Solution ((Don't give Handwritten answer))

. Given the information below propose a molecular formula and draw a structure consistent with that formula. Sow your work. 1) mass spec (m/z) 116 ( 100.0 %) , 118 (32.0%) 2)mass spec (m/z): 86 ( 100.0 %), infrared (cm³¹): 1730 (strong)

What are the functional groups?

Want solution ASAP.....

Complete the following answer using the data provided here: Molecular formula: C4H8O2 Important IR data (cm-1):  3280 (broad); 2980-2730 (many); 1690; 1254 All 1H NMR data (ppm, splitting, integration): 11.0 ppm (s), 1; 2.57 ppm (m), 1; 1.07 ppm (d), 6      1. Sketch out a 1H NMR spectrum showing peak locations and peak splitting on a ppm scale for the data provided above. Include the data labels above in your spectrum, but do not show integration lines. 2. draw the most proper line bond structure for the data given above

I'm about to have an organic chemistry test tomorrow and I don't fully understand the purpose of Mass Spectrometry. Can you please explain why it is used, is the molecule destroyed after (unlike IR spec), and any other useful details? I understand that IR spec is for identifying functional groups and together with NMR we can predict a likely compound.Where does mass spec come into play?Thank you!
