Need help proposing a structure given the following data. Thank you. 24. M = 122, IR peaks near 1500, 1600 and a strong broad peak near 3350 cm! The carbon-13 NMR shows six lines. The 'H NMR spectrum is tabulated below. 7.15 ppm (5H multiplet) 3.75 ppm (2H triplet) 2.75 ppm (2H triplet)
HW4. A student ran a reaction and obtained the following data for an unknown by-product C that contains an alcohol functionality. Alcohol C was purified by column chromatography. Fill in the data below Molecular Formula of C (derived by Mass Spec. analysis): C&H14O The degrees of unsaturation is: Given the degrees calculated, this means: (a) (b) The FT-IR for the unknown alcohol C 100 50- 0- 1000 2000 wavenumber (cm) 3000 1500 500 4000 Bond vibration (e.g. stretch or bend)...
Hi could you help me with this problem please? The following spectroscopic data were obtained for an organic compound: i. MS (relative abundance in parentheses): M+ = 86 ; signals at 29 (92) and 41 (100) among others ii. IR (cm-1): 3100 (weak sharp), 2970 (medium sharp), 2850 (medium), 1650 (weak sharp), 1100 (strong sharp) iii. H1 NMR : Signal A at 4 ppm (3H, triplet), Signal B at 3.53 ppm (2H quartet), Signal C at 4.01...
(a) From the spectral data ( H, C NMR, IR, MS) you were given, identify the structure of your product. Explain why you chose your particular product based on the spectroscopic data. (b) Fully assign the 1H NMR spectrum of your product (i.e. determine which peaks in the 1H NMR correspond to which hydrogens in the product). You will not receive full marks for determination of the unknown unless you assign the 1H NMR spectrum completely. (c) Now work backwards...
Evaluate and investigate the following IR Spectrum and 1H NMR Spectrum. Identify the most important peaks and correlate the results as much as you can from the obtained product in the multi-step synthesis of ethyl acetoacetate. This is Product C from this multi-step synthesis where Product B was identified as in the figure below and as such, identify what product can be obtained after the synthesis from the spectra provided. Use the template below in analysing the spectra. Figure 1...
Assignment For this discussion, you are asked once again to select organic compound from your text book or one that you found on the list of ingredients from a product in your home or select your favorite organic compound. No ionic compounds! The compound of your choice must be an organic compound. Please make sure you are able to answer the following questions regarding the compound of your choice. You may have difficulty answering the questions below if your compound...
Based on the Wittig Reaction exp. below, please answer a) and b). In b) you can disregard the part about the IR, just please interpret and assign protons, shift values, which protons are for which groups, etc on the HNMR. The % yield was 34%, and MP was lower than expected (to assist with answering part a). This should be all the information you need to answer the question. HNMR Discuss the percentage yield of the reaction. Explain and provide...
Label the NMR structure and IR peaks on the carbonyl condensation and answer the questions please Part 1: Draw the structure of the product and show all bonds to the hydrogens. Label the different sets of hydrogens (i.e. Ha. Hb, H1, H2, etc.) based on which ones are equivalent and which ones are not. Create a table that summarizes the chemical shift, integration, multiplicity, the proton assignment, and justification of each signal. Part 2: Explain how the IR spectrum allow...
Evaluate and investigate the following IR Spectrum, 13C NMR Spectrum and 1H NMR Spectrum. Identify the most important peaks and correlate the results as much as you can from the obtained product in the multi-step synthesis of ethyl acetoacetate. This is Product E from this multi-step synthesis where Product C was identified as in the figure below and as such, identify what product can be obtained after the synthesis from the spectra provided. Use the template below in analysing the...
