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.

What is the relationship between protons if swapping them results in the same molecule?

• Heterotopic

• Diastereotopic

• Enantiotopic

• Homotopic

In the context of the video, what is the result of swapping hydrogens with chlorine in a molecule with a chiral center?

• The molecule becomes achiral

• The molecule forms diastereomers

• The molecule forms enantiomers

• The molecule remains unchanged

What is the term for protons that, when swapped, result in a molecule with different stereochemistry at a chiral center?

• Heterotopic

• Enantiotopic

• Diastereotopic

• Homotopic

Which type of protons are identified when symmetry in a molecule results in no new chiral centers upon swapping?

• Enantiotopic

• Heterotopic

• Diastereotopic

• Homotopic

What relationship do protons have if swapping them results in different structural isomers?

• Homotopic

• Diastereotopic

• Enantiotopic

• Heterotopic

What is the relationship between protons if swapping them creates enantiomers?

• Heterotopic

• Homotopic

• Diastereotopic

• Enantiotopic

In the video, what is the significance of a π bond in determining the relationship between protons?

• It makes the protons homotopic

• It creates a new chiral center

• It has no effect on chirality

• It makes the protons heterotopic
