- Given the IR spectra of cis-4-cyclohexene-1.2-dicarboxylic acid and 2-phenyl-2-propanol , interpret the spectras and account for all necessary peaksarrow_forwardPropose a structure consistent with each set of data. C8H10 : IR absorptions at 3108–2875, 1606, and 1496 cm−1arrow_forwardCompound: 4,5-dimethyl-4-cyclohexene-cis-1,2-dicarboxylic acid anhydride or C10H12O3 Label all IR peaksarrow_forward
- Label the 13C spectrum of (R,R)-N,N’-bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediamine peaks and explain why they appear at the ppm that they show up at.arrow_forwardGrignard reagents undergo a general and very useful reaction with ketones. Methylmagnesium bromide, for example, reacts with cyclohexanone to yield a product with the formula C7H14O. What is the structure of this product if it has an IR absorption at 3400 cm-1?arrow_forwardThe intensities of peaks at 69 m/z, 70 m/z, and 71 m/z are 1.2, 31.2, and 1.7, respectively. How many carbons does the compound have?arrow_forward
- For each compound shown below,(1) sketch the 13C NMR spectrum (totally decoupled, with a singlet for each type of carbon), showing approximatechemical shifts.(2) show the multiplicity expected for each signal in the off-resonance-decoupled spectrum.(3) sketch the spectra expected using the DEPT-90 and DEPT-135 techniques. H2C CH CH2Cl3-chloropropenearrow_forwardThese are the characteristics of the IR spectrum, what type of molecule is formed? can you show the drawing.
