Functional Group Map Flashcards
Alcohol - aldehyde
Primary alcohol, acidified potassium dichromate(VI), distillation (orange to green)
Oxidation
Alcohol - ketone
Secondary alcohol, acidified potassium dichromate(VI), reflux (orange to green)
Oxidation
Alcohol - carboxylic acid
Primary alcohol, acidified potassium dichromate(VI), reflux (orange to green)
Primary alcohol - aldehyde - carboxylic acid
Oxidation
Carbonyl - Cyanohydrin
HCN (aq)
Nucleophilic addition
Acid anhydride - ester
Anhydrous alcohol/phenol (acid anhydride is v reactive)
Reflux
Esterification (condensation)
Carboxylic acid - ester
Alcohol, conc. H2SO4 (sulphuric acid), reflux
Esterification (condensation)
Sulphuric acid is a drying agent as it is hygroscopic so it absorbs water and pushed equilibrium further to the right
Ester - carboxylic acid
Dilute HCl/NaOH, reflux
Hydrolysis
Acyl chloride - ester
Alcohol/phenol, room temperature
Acyl chlorides are v v reactive
Esterification (condensation)
Acyl chloride - primary amide
Concentrated ammonia, room temperature
Condensation
Acyl chloride - secondary amide
Amine, reflux
Condensation
Amide - carboxylic acid
Dilute HCl, reflux
Hydrolysis
Amide - amine
Dilute NaOH, reflux
Hydrolysis
Alkene - alkane
- Nickel catalyst, 150degrees, 5atm
- Platinum catalyst, room temperature
Addition (hydrogenation)
Alkene - alcohol
- Conc. phosphoric acid (H3PO4), steam, 300degrees, 60atm
- Conc. H2SO4, water, warm up
Addition
Alkene - halogenoalkane (single Br)
HBr (aq), room temperature (20degrees)
Addition
