Ketone - Coggle Diagram
Ketone
Reduction
Ketone + reducing agent -> secondary alcohol
Reagent used is NaBH4 or LiAlH4 and in dry ether
Iodoform Test
Ketone + I2 -> Sodium Salt + Iodoform
Condition: Iodine is in Alkaline Solution, NaOH
Yellow precipitate can be observed
Nucleophilic Addition
Ketone + HCN -> Hydroxycyanide
Condition: requires heat, KCN as catalyst
Created by
Oxidation of Alkene
Alkene + KMnO4 -> Ketone
Condition: KMnO4 needs to be hot and Alkene must have 2 alkyl groups
KMnO4 turns from purple to colourless
Oxidation of secondary alcohol
Secondary alcohol + oxidising agent -> ketone + water
Condition: heated under reflux
Regeant used is Acidified Potassium Dichromate (VI) or Acidified Potassium Manganate
Potassium Dicchromate turns from Orange to Green
Potassium Manganate turns from Purple to Colourless
Condensation
Requires 2,4-DNPH
Orange precipitate can be observed
