@peakmcat: One of the highest-yield organic chemistry rules on the MCAT👇 Know the difference between PCC and strong oxidizing agents and you’ll answer a ton of oxidation questions with confidence. ✅ PCC → Primary alcohol → Aldehyde ✅ Chromic acid (Jones reagent), KMnO₄ → Primary alcohol → Carboxylic acid Mnemonic: PCC = Pauses at the aldehyde. Strong oxidizers finish the job. Save this for your MCAT review and send it to a friend who keeps mixing these up. ⛰️📚 #MCAT #MCATPrep #Premed #OrganicChemistry #PremedLife
