Please what molecule is this

## Infrared (IR) Spectrum and Nuclear Magnetic Resonance (NMR) Analysis of Molecule 3 ### Infrared (IR) Spectrum - **X-Axis (Wavenumber)**: The x-axis represents the wavenumber in cm⁻¹ (ranging from 4000 to 500 cm⁻¹). - **Y-Axis (% Transmittance)**: The y-axis displays the percentage transmittance. - **Key Absorptions**: - **Alkane Stretching**: Around 2900 cm⁻¹, there's a notable absorption corresponding to C-H (sp³) stretching. - The rest of the spectrum shows minor to moderate absorptions which could be associated with various alkane functional group vibrations. ### Nuclear Magnetic Resonance (NMR) Spectrum - **X-Axis (Chemical Shift, δ)**: The x-axis shows the chemical shift in parts per million (ppm), ranging from 2.0 to 0.0 ppm. - **Key Peaks**: - **Octet at ~1.4 ppm**: Corresponds to a proton environment, labeled as a multiplet. - **Singlet at ~0.9 ppm**: Represents another distinct proton environment, labeled with an intensity of 12. These spectra collectively provide information on the chemical structure of Molecule 3, including the presence of alkane chains and proton environments visible in the NMR spectrum.
