Study notes
Which gives iodoform test: CH₃COCH₃, CH₃CH₂COCH₃, PhCOCH₃, CH₃CHO? Step 1: Need CH₃CO– or CH₃CH(OH)– group. Step 2: CH₃COCH₃ (acetone): yes → yellow CHI₃. Step 3: CH₃CH₂COCH₃: CH₃CO– present → yes! Step 4: PhCOCH₃: CH₃CO– → yes. CH₃CHO: oxidized to CH₃CO– in situ → yes. All four positive!
