Oxidizing Alcohols: PCC vs Jones (Cr(VI)): Mechanism + Exam Traps
Predict oxidation products: PCC stops at aldehydes (from 1° alcohols), while Jones (chromic acid) gives carboxylic acids; both oxidize 2° → ketones.
Reaction: Oxidizing Alcohols: PCC vs Jones (Cr(VI))
What it does: Predict oxidation products: PCC stops at aldehydes (from 1° alcohols), while Jones (chromic acid) gives carboxylic acids; both oxidize 2° → ketones.
Typical reagents: PCC, CH2Cl2
Key intermediate: Varies / context-dependent
Driving force: Formation of strong C=O / oxidation state stabilization
