- The 1H-NMR spectrum of 1-bromopropane shows three signals and the 1H-NMR spectrum of 2-bromopropane shows two signals. Draw these two molecules and determine the relative integrals of each signal.arrow_forwardBased on the spectra you located, does your molecule have a carbonyl? If so, what functional group is it a part of (carboxylic acid, ketone, aldehyde, ester, amide) and what is the frequency (in wavenumbers) of the absorption peak? If not, what is the approximate frequency range for a carbonyl? Does your molecule have either an –O-H or –N-H bond? If so, what functional group is it a part of (carboxylic acid, alcohol, amine, amide) and what is the frequency (in wavenumbers) of the absorption peak? If not, what are the approximate frequency ranges for an –O-H and an –N-H bond? Does your molecule have either an alkyne or nitrile functional group? If so, which functional group is it and what is the frequency (in wavenumbers) of the absorption peak? If not, what is the approximate frequency range for a triple bond?arrow_forwardQ1: Consider the two spectra shown below. One is for 3-methyl-1-cyclopentanone and the other one is for 3-methyl-1-cyclohexanone. Identify which spectra belongs to one compound explain your reasoning.

- Analyze the 1H NMR of 2-phenyl-2-propanol. Based on intensities and splitting patterns, it should be possible to assign all of the peaks in this spectrum. Analyze the 1H NMR of 2-cyclohexyl-2-propanol. In this case, it is not possible to assign all peaks. Indicate which peaks can be assigned to specific H atoms in this compound.arrow_forwardI really need help analyzing and interpreting these spectra to find a chemical formula and compound structure!arrow_forwardSelect all the compounds that exhibits a proton spectrum with only one signal. 2,2-dimethylpropane 1,1-dichloroethane propanone propane cyclopentane 1,2-dichloroethane | benzene | Tetra methyl silane 1,4-dimethylbenzenearrow_forward
- For each of the ten spectra, you should determine which peaks are the most important for identification purposes, what their wavenumber values are, and what specific bonds and/or functional groups they indicate. Record those in the spaces under each spectrum. You don’t have to use each space. Then, from the list of possible compounds, identify what compound is responsible for each spectrum. Realize that these are all the real samples and there may be impurities present that cause weak peaks which would not normally be caused by the compound, such as the one at 3450 cm-1 in Spectrum 1.arrow_forwardFor each of the ten spectra, you should determine which peaks are the most important for identification purposes, what their wavenumber values are, and what specific bonds and/or functional groups they indicate.

Identify a specific absorption band which identifies each characteristic functional group of the molecule chosen.arrow_forwardEach of the following molecules has a unique 1H NMR spectrum. Choose the molecule(s) that will only show two signals, with an integration ratio of 2:3, in their 1H NMR spectrum.arrow_forward
