Front (Question)

Describe an aliphatic amine

Back (Answer)

Contains aliphatic -R groups such as alkyl chains which donate electron density

Front (Question)

Describe an aromatic amine

Back (Answer)

Contains aromatic-R groups such as phenyl which withdraw electron density

Front (Question)

State the functional group of an amide

Back (Answer)

-RCONH2

Front (Question)

Describe a primary amide

Back (Answer)

1 -R 2 -H

Front (Question)

Describe a secondary amide

Back (Answer)

2 -R 1 -H

Front (Question)

Describe a tertiary amide

Back (Answer)

3 -R 0 -H

Front (Question)

Describe an ammonium ion (quaternary ammonium salt)

Back (Answer)

3 groups Fourth group forms dative covalent bond with lone pair on N N has positive charge

Front (Question)

Give two uses of quaternary ammonium salts

Back (Answer)

Hair conditioners Fabric softeners

Front (Question)

Give the equation, reagent and conditions for the reduction of nitriles to form aliphatic amines

Back (Answer)

RCN + 2H2 -> RCH2NH2 Hydrogen, nickel catalyst or LiAlH4 in dry ether

#10

Front (Question)

Give an advantage of preparing amines by reducing nitriles over nucleophilic substitution of haloalkanes

Back (Answer)

Higher yield of desired product as only one product is formed

#11

Front (Question)

Give the equation, reagent and conditions for the nucleophilic substitution of haloalkanes to form aliphatic amines

Back (Answer)

RX + 2NH3 -> RNH2 + NH4X Excess ammonia dissolved in ethanol Heated in a sealed glass tube

#12

Front (Question)

Give the major product of the nucleophilic substitution of haloalkanes to form aliphatic amines when excess ammonia is used

Back (Answer)

Primary amine

#13

Front (Question)

Give the major product of the nucleophilic substitution of haloalkanes to form aliphatic amines when excess haloalkane is used

Back (Answer)

Secondary / tertiary amines or quaternary ammonium salt Successive substitution is likely

#14

Front (Question)

Give the equation, reagent and conditions for the reduction of nitro compounds to form aromatic amines

Back (Answer)

C6H5NO2 + 6[H] -> C6H5NH2 + 2H2O Heat under reflux with Sn and excess conc. HCl No other reagents can be used

#15

Front (Question)

Describe a phenyl amine

Back (Answer)

1 phenyl (C6H5) 2 -H

#16

Front (Question)

Describe a diphenyl amine

Back (Answer)

2 phenyl (C6H5) 1 -H

#17

Front (Question)

Describe a triphenyl amine

Back (Answer)

3 phenyl (C6H5) 0 -H

#18

Front (Question)

Which amine is the strongest base?

Back (Answer)

Tertiary amine

#19

Front (Question)

Which amine is the weakest base?

Back (Answer)

Triphenyl amine

#20

Front (Question)

Describe why amines with alkyl groups are strong

Back (Answer)

Alkyl groups donate electrons (aliphatic) Lone pair is more available to react

#21

Front (Question)

Describe why amines with phenyl groups are weak

Back (Answer)

Phenyl groups withdraw electrons (aromatic) Lone pair is less available to react
