How many peaks should we see in the Carbon-13 NMR Spectrum of Propan-2-ol?
Question
How many peaks should we see in the Carbon-13 NMR Spectrum of Propan-2-ol?
Solution
In the Carbon-13 NMR Spectrum of Propan-2-ol, we should see three peaks. Here's why:
-
Propan-2-ol has the molecular formula CH3CHOHCH3.
-
In this molecule, there are three types of carbon environments.
-
The first type is the carbon in the -CH3 group. There are two of these, but they are in the same environment, so they give rise to one peak.
-
The second type is the carbon in the -CHOH- group. This is a unique environment, so it gives rise to a second peak.
-
Therefore, in total, we should see three peaks in the Carbon-13 NMR Spectrum of Propan-2-ol.
