Amides

Question 1

Amide Functional Group

Answer 1

-CONH2

Question 2

How are amides named

Answer 2

From the Carboxylic Acid (methanoic acid -> methanamide)

Substituent must number from the carbon in amide group

Question 3

Methanamide

Answer 3

Liquid at Room temp
HCONH2

Question 4

Other Longer Chain Amides State

Answer 4

Solid At Room Temp

Question 5

Two Ways To Prepare Amide

Answer 5

•dehydration of an ammonium salt of a carboxylic acid

•acyl chloride w/ amine

Question 6

Dehydration of an Ammonium Salt of a Carboxylic Acid

Answer 6

Heating an ammonium salt of CA causes it to dehydrate to form an amide

Question 7

Acyl Chloride w/ Amine

Answer 7

Reacts to form an N-substituted amide

Question 8

Acid Hydrolysis of Amide

Answer 8

Prod CA and ammonium salt of dilute acid

Incl H2O and HCl

Question 9

Alkaline Hydrolysis

Answer 9

Prod salt of CA and ammonia gas

Question 10

Dehydration of Amides

Answer 10

Distill over Phosphorus Pentoxide, P2O5

Form Nitriles

Question 11

Dehydration

Answer 11

Reaction that involves the elimination of water from the amide, forming a nitrile

Question 12

Basic Strength

Answer 12

Amides poor bases
Delocalisation of N atom with pi bond of C=O - lone pair more stable

Question 13

Order of Basicity

Answer 13
