Flashcards in H-NMR Deck (11)
H on a Phenol
About 4-7 ppm
Carboxylic Acid Hydrogen
When a carbon is bonded to two H's and two nonequivalent groups, the H's are enantiotopic.
They are chemically equivalent so they show up as ONE signal on the NMR.
When a carbon bound to an asymmetric center is also bound to two H's, the H's are diastereotopic.
The H's are NOT chemically equivalent so they will show up as TWO signals in the NMR
