The 13-C NMR Spectrum for Propan-2-ol has 2 peaks. One peak is situated at 25 ppm, and the second peak appears at 64ppm. Identify which Carbon Environment is responsible for the peak at 64 ppm. (1 Point)

Propan-2-ol has three carbon atoms. The carbon atom in the middle (C2) is attached to an oxygen atom and two other carbon atoms. This makes it a unique environment compared to the other two carbon atoms (C1 and C3), which are only attached to hydrogen atoms and other carbon atoms.

In NMR spectroscopy, the chemical shift (measured in ppm) is influenced by the electron density around the atom. The more electronegative atoms (like oxygen) decrease the electron density around the attached carbon atom, which results in a higher chemical shift.

Therefore, the peak at 64 ppm in the 13-C NMR spectrum of propan-2-ol corresponds to the carbon atom attached to the oxygen atom (C2).
