**Consider the multiplicity of the ¹H NMR peak shown below.**

**Identify how many hydrogens are on the neighboring carbon(s).**

### Explanation of the NMR Peak:

The image shows an NMR spectrum with a peak that appears as a quintet, indicating five distinct splitting patterns. This suggests that there are four hydrogen atoms on the neighboring carbon atoms. According to the N+1 rule in NMR spectroscopy, the number of peaks (multiplicity) is equal to the number of neighboring hydrogens plus one. Thus, a quintet corresponds to four neighboring hydrogens.

### Hydrogen Selection Panel:

On the right side of the image, there is a numerical keypad with numbers from 1 to 9, a plus/minus button, a decimal point, and a zero. This allows the user to input the number of hydrogens on neighboring carbon(s), based on their analysis of the NMR peak’s multiplicity.
