11. Acyl chlorides

Question 1

functional group

Answer 1

R-COCL e.g. CH3COCl (double bond O)

Question 2

why are they very reactive

Answer 2

Cl can be substituted for other groups

Question 3

root and suffix and example

Ch3COCl

Answer 3

root - number of Cs
suffix - oyl chloride
ethanoyl chloride

Question 4

reagents (making an acyl chloride)

Answer 4

carboxylic acid and SOCl2

Question 5

products (making an acyl chloride)

Answer 5

R-COCL + SO2 + HCl

acyl chloride + sulfur dioxide + hydrogen chloride gas

Question 6

equation (formation of acyl chloride)

methanoic acid

Answer 6

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

Question 7

how to seperate acyl chloride from reaction mixture

Answer 7

distillation

Question 8

products

acyl chloride + alcohol ->

Answer 8

ester + HCl

Question 9

acyl chloride + concentrated ammonia ->

Answer 9

primary amide + solid ammonium chloride

Question 10

equation (acyl chloride + concentrated ammonia)

ethanoyl chloride + concentrated ammonia ->

Answer 10

acyl chloride + ammonia -> primary amide + ammonium chloride

CH2COCl + 2NH3 -> CH3CONH2 + NH4Cl

ethanoyl chloride + concentrated ammonia -> ethan amide + ammonium chloride

Question 11

equation (acyl chloride + alcohol)

ethyl chloride + methanol->

Answer 11

acyl chloride + alcohol -> ester + hydrogen chloride

CH3COCl + CH3OH -> CH3COOCH3 + HCL

methanoyl chloride + methanol -> ethyl methanoate +

Question 12

Acyl Chloride + primary amide->
equation
CH3COCl + CH3CH2NH2 ->

Answer 12

secondary amide + HCl

CH3CONHCH2CH3 + HCl

butan amide + hydrogen chloride
