To analyze the given H NMR spectra of isomeric alcohols with the formula C5H12O and assign the signals for each hydrogen (H) in the molecule, you would first need to understand how to interpret an H NMR spectrum.

H NMR (or proton NMR) spectroscopy provides information about the chemical environment of hydrogen atoms in a molecule. Each distinct chemical environment leads to a distinct signal (peak) in the spectrum. The chemical shift (δ) of a signal is measured in parts per million (ppm) and represents its position on the spectrum. The integration (area under the peak) indicates the relative number of hydrogens contributing to that signal. Coupling patterns (splitting) can also help determine the connectivity of neighboring hydrogens.

Since you mentioned a link to an image, I cannot directly view or access it. However, I can guide you on how to interpret the spectra and assign signals based on the expected number of signals for each isomer. Here's the step-by-step approach:

1. Determine the expected number of signals for each isomer:
- Look at the molecular formula (C5H12O). Count the total number of unique hydrogen environments.
- Consider the possible isomers (structural arrangements) of C5H12O: pentanol, 2-methylbutanol, 2-methyl-2-butanol, and 3-methylbutanol.
- Each isomer will have different chemical environments, leading to a different number of signals.

2. Identify the signals (peaks) in the spectra:
- Examine the spectra and locate the distinct signals (peaks) that represent the different chemical environments.
- Count the number of unique signals present in each spectrum.

3. Assign signals to each H in the molecule:
- Assign each signal (peak) to the corresponding hydrogen (H) in the molecule based on the expected number of signals and the connectivity of neighboring hydrogens.

Without the specific details of the spectra and isomers, I cannot provide a structure or assign signals for each hydrogen. However, by following the steps mentioned above, you should be able to analyze the spectra and assign signals based on the given information.
