Practice Problem: Types of Protons

The video tutorial explains how to determine the relationship between pairs of protons in molecules, categorizing them as homotopic, enantiotopic, diastereotopic, or heterotopic. It provides examples for each type, illustrating the process of redrawing molecules and swapping hydrogens to assess stereochemistry and structural differences. The tutorial emphasizes the importance of chiral centers, symmetry, and structural isomers in identifying these relationships.

In the example with bromobenzene, what type of relationship do the two hydrogens exhibit?

How does the presence of a π bond affect the relationship between protons?

What conclusion can be drawn about the protons in the last example discussed?
