Please what molecule is this

### Infrared (IR) and Nuclear Magnetic Resonance (NMR) Spectra Analysis of Molecule 21 #### Infrared (IR) Spectrum - **Graph Description:** - **Y-axis:** % Transmittance - **X-axis:** Wavenumber (cm⁻¹) - **Peak Analysis:** - **Ketone Region:** A distinct peak indicating the presence of a ketone functional group is visible around the 1700 cm⁻¹ region, representing the carbonyl (C=O) stretching vibration. - **CH (sp³) Stretching:** A peak around 3000 cm⁻¹ indicates the presence of sp³ hybridized carbon-hydrogen bonds, typical for alkanes. - **Other Peaks:** Various less intense peaks over the range from 1500 to 500 cm⁻¹ represent other bending and stretching vibrations related to the molecular structure. #### Nuclear Magnetic Resonance (NMR) Spectrum - **Graph Description:** - **Y-axis:** Intensity - **X-axis:** Chemical Shift (δ, ppm) - **Peak Analysis:** - **δ 2.6 ppm (Sextet):** The signal indicates a complex splitting pattern suggesting six neighboring hydrogens influencing the peak. - **δ 2.2 ppm (Singlet, labeled as 3):** Represents a single type of hydrogen environment with no coupling evident, possibly indicating a methyl group adjacent to a non-hydrogen environment. - **δ 1.4 ppm (Quintet):** Implies a coupling pattern from four neighboring hydrogens. - **δ 1.0-0.8 ppm (Multiplets labeled as 3):** These peaks suggest further multiplicity possibly from CH₃ groups in different environments within the molecule. These spectral analyses provide insights into the structural and functional makeup of Molecule 21, aiding in determining the molecular framework and chemical environment.
