- Please solve this organic chemistry question A carboxylic acid with the molecular formula C5H10O2 is treated with thionyl chloride to give compound A. Compound A has only one signal in its 1H NMR spectrum. Please figure out this carboxylic acid. You can write out name directly or molecular formula with functional groups (e.g. isopropanol (CH3)3COH). Hint: Only one H NMR signal means all hydrogens are in the same chemical status.arrow_forwardWhat is this compound base on the IR spectrum?arrow_forward3. a) Draw the below structure and answer the following questions. CI CH2COCH2CH3 i. Identify the chemically equivalent protons in the structure. Explain your answer. ii. Mention how many peaks you would expect in the HNMR spectrum of the compound. Explain the position of each peak in the spectrum. iii. Mention what would be the splitting pattern of each peak with proper explanation. iv. Draw the HNMR spectrum of the compound. b) Explain why the delta/ ppm scale was introduced instead of Hz in NMR analysis with example.arrow_forward
- True or False 1. A molecule that is "IR inactive" means that it does not produce any signal due to no vibration. 2. Infrared spectroscopic data is reported in wavenumber (cm-1) against absorbance because they have a linear relationship. 3. The signals observed from a molecule of chloropropane will have a higher wavenumber than iodopropane. 4. The signals observed from the C-C bond in an alkene will report at a higher wavenumber than the C-C bond in an alkyne.arrow_forwardBelow are three MS spectra, Spectra 1, 2, and 3. Each of this mass spectrum corresponds to either Compound A (contains one Cl in the molecular formula), Compound B (one I in the molecular formula), and Compound C (one Br in the molecular formula). Identify which spectra corresponds to which compound. Provide explanations for your choices.arrow_forwardWhich one of the pi bonds in the molecules shown below will produce a stronger signal in an IR spectrum? Yes, compound I produces a stronger signal because it has a larger dipole moment. O Yes, compound II produces a stronger signal because it has a larger dipole moment. No, the alkene groups produce similar signals because they have similar double bonds. O No, the alkene groups produce similar signals because they both contain a similar number of atoms.arrow_forward
