11. Acyl chlorides Flashcards
functional group
R-COCL e.g. CH3COCl (double bond O)
why are they very reactive
Cl can be substituted for other groups
root and suffix and example
Ch3COCl
root - number of Cs
suffix - oyl chloride
ethanoyl chloride
reagents (making an acyl chloride)
carboxylic acid and SOCl2
products (making an acyl chloride)
R-COCL + SO2 + HCl
acyl chloride + sulfur dioxide + hydrogen chloride gas
equation (formation of acyl chloride)
methanoic acid
carboxylic acid + Thionyl chloride -> acyl chloride + sulfur dioxide + hydrogen chloride gas
CH3COOH + SOCl2 -> CH3COCl + SO2 + HCl
methanoic acid + thionoyl chloride -> ethyl propanoyl + sulfur dioxide + hydrogen chloride gas
how to seperate acyl chloride from reaction mixture
distillation
products
acyl chloride + alcohol ->
ester + HCl
acyl chloride + concentrated ammonia ->
primary amide + solid ammonium chloride
equation (acyl chloride + concentrated ammonia)
ethanoyl chloride + concentrated ammonia ->
acyl chloride + ammonia -> primary amide + ammonium chloride
CH2COCl + 2NH3 -> CH3CONH2 + NH4Cl
ethanoyl chloride + concentrated ammonia -> ethan amide + ammonium chloride
equation (acyl chloride + alcohol)
ethyl chloride + methanol->
acyl chloride + alcohol -> ester + hydrogen chloride
CH3COCl + CH3OH -> CH3COOCH3 + HCL
methanoyl chloride + methanol -> ethyl methanoate +
Acyl Chloride + primary amide->
equation
CH3COCl + CH3CH2NH2 ->
secondary amide + HCl
CH3CONHCH2CH3 + HCl
butan amide + hydrogen chloride
