3.9 Carboxylic Acids And Derivatives

Question 1

Why are acyl chlorides so reactive?

Answer 1

Two highly electronegative atoms bonded to the carbon making it very polar so is readily attacked by nucleophiles

Question 2

What type of reactions do acyl chlorides undergo?

Answer 2

Nucleophilic addition-elimination

Question 3

Why are anhydrides preferred over acyl chlorides?

Answer 3

Anhydrides are cheaper and less dangerous because there is no Chlorine present which forms corrosive HCL fumes

Question 4

What can acyl chlorides react with?

Answer 4

Water,Alcohols, Ammonia and Amines

Question 5

What is the amide functional group?

Answer 5

ONH2

Question 6

What does Acylchloride + water form?

Answer 6

Carboxylic acid + HCl

Question 7

What does acyl chloride + Ammonia form?

Answer 7

______ Amide

Question 8

What does acyl chloride + amine form?

Answer 8

N-______thyl_____amide + HCl

Question 9

What does acyl chloride + alcohol form?

Answer 9

Ester + HCl

Question 10

What do anhydrides always form when reacted with anything acyl chlorides react with?

Answer 10

Carboxylic acid
