The structure identified is 2-methylbutan-1-ol based on the spectral analysis. The compound has zero degrees of unsaturation and matches spectral data well.
Here are the step-by-step steps to solve this:

Determine the Degree of Unsaturation: For C₅H₁₂O, the Index of Hydrogen Deficiency (IHD) is zero, indicating no double bonds or rings.

Analyze the ¹H NMR Spectrum: Look at the number of signals, their chemical shifts, multiplicities, and integrations to identify functional groups and their environment.

Analyze the ¹³C NMR Spectrum: Determine the number and types of carbon environments.

Analyze the IR Spectrum: Identify key functional group absorptions, especially around 3300 cm⁻¹ (alcohol hydroxyl group) and 3000-2850 cm⁻¹ (C-H stretch).

Propose Possible Structures: Compare the spectral data to determine the most plausible structure.


Given the lack of strong IR bands above 3000 cm⁻¹ or at 1700 cm⁻¹, and integrating ¹H NMR data, potential constitional isomers include pentan-1-ol, pentan-2-ol, 2-methylbutan-1-ol, and 3-methylbutan-2-ol.
IR, NMR, and other data will narrow to the specific structure.
The IUPAC name for the structure derived is 2-methylbutan-1-ol.
