NMR Spectroscopy

NMR stands for Nuclear Magnetic Resonance in which the study of different molecules is done based on the interaction of radiofrequency electromagnetic radiations with the nuclei of molecules placed in a strong magnetic field. A precise study of spectra of visible light and all bands of electromagnetic radiation is called spectroscopy.

Question

A \( ^1H \) NMR spectrum of the molecule shown below was prepared in deuterated acetone. \( D_2O \) was added to the sample and then another spectrum was obtained.

Identify the peak(s) that no longer appear in the spectrum.

**Diagram Description:**

The molecular structure has three hydrogen atoms labeled:
- **I** attached to an oxygen (hydroxyl group).
- **II** connected to a carbon in the carbon chain.
- **III** is another hydrogen in the carbon chain.

**Multiple Choice Options:**

A) I
B) II
C) III
D) I and II
E) II and III
