Question 40 of 40 Consider the following two compounds. Determine how UV spectroscopy could be used to differentiate between the two molecules. Submit A Compound I will have a larger λ(max). B Compound II will have a larger λ(max). C These two compounds will be indistinguishable by UV spectroscopy.

Need a help a little with HNMR question please! Thank you Part 3B Set 1. Can 1H NMR spectroscopy be used to differentiate between the two compounds? Briefly explain why or why not. Predict the 1H NMR spectrum for each compound (include integration, multiplicity, and approximate chemical shift). Either draw the actual spectrum or put in a data table format.

How could spectroscopy be used to support that the below reaction occurred? Choose all that apply. excess CH HCI H,C, CH3 v 1st attempt Choose one or more: O Use IR; the product has a strong broad peak at 2200 cm-1, but the starting material does not. O Use UV-vis; the product would not show an absorbance in the spectrum range due to a shorter Åmax from that of the starting material O Use IR; the product has a sharp narrow peak at 3300 cm-1, but the starting material does not. O IR will not be useful as no detectable change in the spectrum will occur. O UV-vis will not be useful because no change in åmax Would occur. Use IR; the starting material has a sharp narrow peak at 3300 cm-1, but the product does not. Use UV-vis; the product would show an absorbance at a longer Âmax from that of the starting material. O Use IR; the starting material has a strong broad peak at 2200 cm-1, but the product does not.

How could 1H NMR spectroscopy be used to distinguish betweencompounds X and Y?

Hi I know that the red is the correct one and it's like the nmr but Chan you explain why. Also in the nmr can you tell me which peak it's important and if it's double triple or single bond with the ratio and compoundstructure.thank you very much .

8. Given the ¹H NMR spectrum provided, give the structure of the molecule. The IR shows two strong peaks at 1750 cm¹ and 3400 cm¹. The molecular formula is C3H6O2. Integrations are given below. —|- 10 1H 9 8 6 7 Chemical Shift (ppm) 1H 5 2H 3 2H 2

OChem Help... Explain how you might distinguish between the following two compounds by comparing their 1H-NMR and their DEPT 135 spectra. Provide the bond line structures for the two compounds Use the correct splitting pattern AND approximate chemical shifts for the peaks given by each compound See attached image Also I did the bond line structures, but can you please check for correctness
