Question
Explain how ‘H NMR spectroscopy could be used to distinguish between these two compounds.

Transcribed Image Text:This image displays two chemical structures of compounds related to the naphthalene series:
1. **Left Structure:**
- This is a naphthalenone compound.
- It consists of a naphthalene ring system with a ketone group (C=O) attached. The ketone group is represented by the "O" with a double bond on top of a hexagonal ring, which is part of the naphthalene structure.
2. **Right Structure:**
- This compound is the alcohol counterpart of the left structure.
- It features a naphthalene ring system similar to the first, but includes a hydroxyl group (OH) replacing the ketone group. The OH group is bonded to the top of the hexagonal ring.
Both structures share a benzene ring fused to a six-membered ring, characteristic of naphthalene derivatives, indicating their aromatic nature.
Expert Solution

Step 1 Introduction
- The 1 H nmr spectrum is very much useful.
- Here in this structure we can easily differenciate between these two compounds using 1 H nmr.
- Here any protons show signal with the protons on neighbouring carbons proton.
