Q

what are the products of an acyl chloride with cold water reaction

A

a carboxylic acid, and an HCl gas that forms misty fumes (so if misty fumes form it can mean a reaction on an acyl chloride)

Q

what further reactions take place after the acyl chloride and concentrated ammonia solution reaction takes place

A

since one of the reactants (NH3) is a base the HCl formed would be an acidic gas so they can react together such as NH3 + HCl —> NH4Cl

Q

what are the products in the reaction of acyl chloride and amines

A

N - subsutited amine and HCl (g) (misty fumes)

16
Q

what does the N in N - substituted amide indicate

A

that the N is attached to an acyl group

17
Q

how do you name N - substituted amides made from primary amines

A

N - the name of ester + amide for example N - methylethananmide

18
Q

what are secondary amine’s general formula

A

R2NH

19
Q

how do you name N - substituted amides made from secondary amines

A

since they contain 2 substituted alkalis they would be written the following way N,N - di name of ester amide for example N,N-diethylethanamide

20
Q

why doesn’t a reaction occur between tertiary amines (R3N) and acyl chlorides

A

there is no H atom to react with cl to form HCl
