Transcribed Image Text:### Analyzing the Multiplicity of a ¹H NMR Peak
#### Instructions:
Consider the multiplicity of the ¹H NMR peak shown below. Identify how many hydrogens are on the neighboring carbon(s).
#### NMR Spectrum Overview:
- **Graph Description**: The NMR spectrum displays a triplet, which indicates a peak with three distinct lines of nearly equal height. This suggests splitting due to hydrogen atoms on adjacent carbon atoms.
#### Numerical Input Interface:
- **Hydrogens Calculator**:
- Number pad available with digits from 1 to 9.
- Includes buttons for decimal point (`.`) and plus/minus (`+/-`).
- This feature enables students to input the number of hydrogens on neighboring carbon atoms based on the observed multiplicity.
#### Explanation:
The presented triplet implies that there are two neighboring hydrogen atoms (n+1 rule of NMR spectroscopy, where n is the number of hydrogens on adjacent carbons). This is a typical splitting pattern observed in proton NMR spectroscopy when interacting hydrogens are present on adjacent carbons.
