## Transcription and Explanation of Spectroscopic Analysis ### Molecular Formula - **C₅H₁₀O** ### Infrared (IR) Spectrum - **Y-axis**: % Transmittance - **X-axis**: Wavenumbers (cm⁻¹) #### Key Peaks: 1. **3400 cm⁻¹**: Indicates the presence of an O-H bond, typical of alcohols. 2. **3000 cm⁻¹**: Associated with C-H stretching in alkanes. 3. **1720 cm⁻¹**: A strong peak characteristic of the C=O (carbonyl) group, often found in ketones or aldehydes. 4. **1500-1000 cm⁻¹ range**: Various peaks indicating C-C stretching and C-H bending. ### Nuclear Magnetic Resonance (NMR) Spectrum - **X-axis**: Chemical shift (ppm) #### Key Peaks: 1. **Around 2.2 ppm**: A peak possibly indicating protons adjacent to a carbonyl group (deshielded). 2. **Around 1.6-1.8 ppm**: Multiple peaks indicating protons on carbons adjacent to a moderately electronegative atom or group. 3. **Around 1.0-0.8 ppm**: Represents protons in methyl groups (alkyl C-H bonds). ### Summary This spectroscopic analysis reveals that the compound with molecular formula C₅H₁₀O likely contains a carbonyl group and possibly an alcohol moiety. These features are supported by the IR and NMR spectral data suggesting both aldehyde or ketone functionalities and potentially an alcohol presence.
