### Chemical Structures - **a)** Structure: Butanone (Methyl ethyl ketone) - **b)** Structure: Tetrahydropyran - **c)** Structure: Pentanal - **d)** Structure: 2-Butanol - **e)** Structure: Cyclopentanol ### Infrared (IR) Spectrum Analysis The IR spectrum is shown with a red line graph on a plot. The x-axis is labeled with values decreasing from 2000 to 1000 cm⁻¹, representing the wavenumber, typically used in IR spectroscopy. The y-axis is labeled from 0.0 to 0.8, possibly indicating transmittance or absorbance. Annotated in the center of the spectrum is a chemical formula: C₅H₁₀O. This indicates that the IR spectrum corresponds to a compound with this molecular formula. ### Graph Description The IR spectrum displayed shows peaks that represent different bond vibrations in a molecule. A brief analysis of typical functional group absorptions could include: - The spectrum might show a peak around 1700 cm⁻¹, indicating the presence of a carbonyl (C=O) group. - Broad peaks could be present around 3200-3500 cm⁻¹, indicative of O-H stretches if the compound is an alcohol or contains a hydroxyl group. - Peaks in the region of 2800-3000 cm⁻¹ are generally associated with C-H stretches in alkanes. These features can help identify the specific structure from the given list that matches the IR spectrum of a compound with the molecular formula C₅H₁₀O.

### Infrared (IR) Spectrum Analysis

The IR spectrum is shown with a red line graph on a plot. The x-axis is labeled with values decreasing from 2000 to 1000 cm⁻¹, representing the wavenumber, typically used in IR spectroscopy. The y-axis is labeled from 0.0 to 0.8, possibly indicating transmittance or absorbance.

Annotated in the center of the spectrum is a chemical formula: C₅H₁₀O. This indicates that the IR spectrum corresponds to a compound with this molecular formula.

### Graph Description

The IR spectrum displayed shows peaks that represent different bond vibrations in a molecule. A brief analysis of typical functional group absorptions could include:

- The spectrum might show a peak around 1700 cm⁻¹, indicating the presence of a carbonyl (C=O) group.
- Broad peaks could be present around 3200-3500 cm⁻¹, indicative of O-H stretches if the compound is an alcohol or contains a hydroxyl group.
- Peaks in the region of 2800-3000 cm⁻¹ are generally associated with C-H stretches in alkanes.

These features can help identify the specific structure from the given list that matches the IR spectrum of a compound with the molecular formula C₅H₁₀O.
