Question

Please what molecule is this

The image features two graphs, which appear to be analytical spectra for Molecule 13. ### Upper Graph: Infrared (IR) Spectrum - **X-axis (wavenumber in cm\(^{-1}\))**: Ranges from 4000 to 500 cm\(^{-1}\). - **Y-axis (% transmittance)**: Indicates the transmittance level. Peaks in the graph correspond to various molecular vibrations that absorb IR radiation. #### Key Peaks: - **Around 3000 cm\(^{-1}\)**: Strong absorption peak labeled as CH (sp\(^3\)), indicating C-H stretching vibrations in sp\(^3\) hybridized carbon atoms. - **Around 2200 cm\(^{-1}\)**: Peak labeled C≡N, likely indicating a nitrile group (C≡N triple bond). - **Around 1600 cm\(^{-1}\)**: Peak labeled C-N, typically associated with C-N stretching vibrations. - A broad label for "nitrile" is placed over the spectrum, likely indicating the presence of a nitrile functional group. ### Lower Graph: Nuclear Magnetic Resonance (NMR) Spectrum - **X-axis (δ in ppm)**: Chemical shift values, from 3.0 to 0.0 ppm. - **Peaks**: - A multiplet around 2.6 ppm, labeled "1". - A sharp singlet around 1.4 ppm, labeled "6", indicating likely proton environments in the molecule. These spectra together help characterize Molecule 13, providing insights into its functional groups and structure.
