Unit 5 - Organic reactions Flashcards
Halogenoalkane to amine
Heat excess alcoholic NH3 (i.e in ethanol) - primary amines
Heat alcoholic NH3 - secondary/ tertiary amines
Aldehyde to carboxylic acid
- In theory, oxidise with acidified potassium dichromate and heat
- However it’s difficult to do
Acyl chloride to carboxylic acid
H2O at room temperature
Alcohol to halogenoalkane
Reflu with NaBr (sodium bromide) and H2SO4
Alcohol to ketone
Heat with acidified potassium dichromate
Acyl chloride to N-substituted amide
Amine at room temperature
Alkene to halogenoalkane
Hydrogen halide at room temperature
Acyl chloride to ester
Alcohol at room temperature
Alkene to alkane
H2 + nickel Catalyst at 150°C
Carboxylic acid to alcohol
LiAlH4 in dry diethyl ether
Carboxylic acid to acyl chloride
PCl5 at room temperature
Alkane to halogenoalkane
Halogen under UV light/radiation = free radical substitution
Alcohol to aldehyde
Heat with acidified potassium dichromate and distill off
Halogenoalkane to alkene
Reflux with sodium hydroxide and ethanol
Halogenoalkane to nitrile
HCN in presence of KCN, with ethanol
