Identify the compound from the compound bank based on the NMR

**Table of Compounds and Their Properties** | Compound Name | Melting Point (°C) | Structure Description | |--------------------------|--------------------|------------------------------------------------------------------| | 9-fluorenemethanol | 105-107 | The structure shows two fused benzene rings with an alcohol (-OH) group attached to a methanol group at the ninth carbon. | | 2-indanol | 68-71 | The structure consists of a saturated five-membered carbon ring with a hydroxyl group (-OH) attached to the second carbon alongside a benzene ring. | | 1-naphthalenemethanol | 61-63 | This compound includes two fused benzene rings with an alcohol (-OH) group attached to a methanol group at the first carbon. | | benzil | 94-95 | The structure shows two benzene rings connected by a carbonyl group (C=O) at each end of a two-carbon chain. | | 4-phenylcyclohexanone | 78-80 | The structure features a six-membered cyclohexanone ring with a phenyl group attached to the fourth carbon. | | 2'-acetonaphthone | 53-55 | This compound includes two fused benzene rings with an acetyl group (CH3-C=O) attached at the second carbon. | | 1-indanone | 40-42 | The structure consists of a benzene ring fused to a five-membered ring with a carbonyl group (C=O) attached to the first carbon. | *Note: The temperatures listed are approximate melting points, indicating the temperature at which each compound transitions from solid to liquid.*

**Component V NMR Analysis** This image contains two NMR (Nuclear Magnetic Resonance) spectra, which are techniques used to determine the structure of organic compounds by analyzing the magnetic properties of atomic nuclei. **Top Graph: Proton NMR Spectrum** - **X-axis:** Chemical Shift (PPM) - **Peaks and Corresponding Hydrogen Integrations:** - At approximately 7.0 to 7.5 PPM: Multiple peaks with integrations labeled as 1H, 1H, 3H, and 1H. These might represent aromatic hydrogens. - At approximately 4.0 PPM: A peak with integration labeled as 2H, possibly indicating a methylene group adjacent to an electronegative atom or group. - At approximately 1.0 PPM: A peak with integration labeled as 1H, which could be indicative of a hydrogen in a less deshielded environment, such as an alkane chain. **Bottom Graph: Carbon-13 NMR Spectrum** - **X-axis:** Chemical Shift (PPM) - **Observations:** - Several prominent peaks, with significant peaks around 120-140 PPM. These peaks could indicate the presence of sp2 hybridized carbons, possibly in an aromatic ring. - A single peak around 60 PPM could suggest an sp3 hybridized carbon, possibly adjacent to an electronegative atom like oxygen. **Analysis Summary:** The NMR spectra present in this image provide insights into the chemical environment and structure of Component V. The proton NMR suggests an aromatic compound with additional functional groups indicated by the peaks at lower chemical shifts. The carbon-13 NMR confirms the presence of sp2 hybridized carbons typical of aromatic rings and potential non-aromatic carbons. Understanding these spectra is critical for deducing the molecular structure of organic compounds.
