#1
Front (Question)

Give the amide functional group

Back (Answer)

RCONR C is double bonded to O

#2
Front (Question)

Give the three different types of amides

Back (Answer)

Primary amide - 2 hydrogens are attached to the nitrogen - ie RCONH2 Secondary amide - one of the groups attached to the nitrogen is a hydrogen, the other is an alkyl group Tertiary amide - both groups attached to the nitrogen are alkyl groups

#3
Front (Question)

Describe how to make a primary amide

Back (Answer)

Acyl chloride + ammonia —> primary amide + hydrochloric acid Eg: RCOCl + NH3 —> RCONH2 + HCl HCl produced can react with another molecule of NH3 to produce NH4+Cl-

#4
Front (Question)

Describe how to make a secondary amide

Back (Answer)

Acyl chloride + primary amine —> secondary amide + alkyl ammonium chloride Eg: RCOCl + 2RNH2 —> RCONHR + RNH3Cl

#5
Front (Question)

Describe how to make a tertiary amide

Back (Answer)

Acyl chloride + secondary amine —> tertiary amide + alkyl ammonium chloride Eg: ROCl + 2RNHR —> RCONRR + RNH3Cl

#6
Front (Question)

What would see when making all types of amides

Back (Answer)

Misty fumes of HCl

#7
Front (Question)

Give the ways in which amides can react

Back (Answer)

Can undergoes hydrolysis Can undergo reduction

#8
Front (Question)

Describe hydrolysis of amides

Back (Answer)

Reflux either under acidic or aqueous conditions Acidic: RCONH2 + H+ + H2O —> RCOOH + NH4+ Alkaline: RCONH2 + OH- (aq) —> RCOO- + NH3 (acidify with a strong acid to obtain carboxylic acid)

#9
Front (Question)

Describe the reduction of amides

Back (Answer)

Amides can undergo reduction to form amines Warm amide with LiAIH4 in dry ether, then follow with hydrolysis of dilute acid Eg: CH3CONH2 + 4[H] —> CH3CH2NH2 + H2O
