1‑Phenylethanol (${\mathrm{C}}_6{\mathrm{H}}_5\mathrm{CH}(\mathrm{OH})\mathrm{C}{\mathrm{H}}_3$) is oxidised with pyridinium chlorochromate (PCC). Identify the major product and provide its common and IUPAC names.

Step-by-step solution

1. Step 1: PCC oxidises primary and secondary alcohols to aldehydes and ketones respectively.
2. Step 2: 1‑Phenylethanol is a secondary alcohol; PCC will oxidise it to a ketone.
3. Step 3: The ketone obtained is ${\mathrm{C}}_6{\mathrm{H}}_5\mathrm{C}(\mathrm{O})\mathrm{C}{\mathrm{H}}_3$, which is acetophenone.
4. Step 4: The common name is acetophenone; the IUPAC name is 1‑phenylethanone.
5. Step 5: Verify that no over‑oxidation occurs because PCC is a mild oxidant.
