Question 7

In the proton NMR spectrum,the indicated CH₂ group will show up as a

Accepted Answer

The CH group adjacent to the indicated group will produce a splitting pattern known as a doublet. This is because the proton on this neighboring CH group will create a magnetic field that will affect the chemical shift of the indicated CH₂ group, causing it to split into two peaks of equal intensity.

Question 20

The indicated hydrogens (H_a and H_b)are

Accepted Answer

The two hydrogens are diastereotopic because they are unique in their chemical environment due to the presence of the nearby sulfur atoms. This means that they will have different chemical shifts in a NMR spectrum and will be affected differently by chiral reagents, making them diastereotopic.
