Question 1

Phenylamine => Bromoaminobenzene
Equation
Type of reaction
Conditions 
Reagents

Answer 1

Equation
-Phenylamine + 3Br2 => 2,4,6-tribromoaminobenzene + HBr
Type of reaction
-Bromination
Conditions
-no halogen carrier catalyst needed as bromine reacts more with Phenylamines NH2 group is activating
Reagents

Question 2

Amino Acid => Ester
Equation
Type of reaction
Conditions 
Reagents

Answer 2

Equation
-Amino Acid + Alcohol => Ester + H2O
E.g. H2NCH2COOH + CH3CH2OH + H+ => H3N+ CH2COO-C2H5 + H20

*don’t forget that the amine group gains a proton from the sulphuric acid

Type of reaction
-Esterification 
-easy reaction
Conditions 
-small amount of concentrated sulphuric Acid
-excess 
Reagents
-Alcohol + H2SO4

Question 3

Acid Anhydride => Carboxylic Acid
Equation
Reagents

Answer 3

Equation
Acid Anhydride + Phenol => Phenylester + Carboxylic Acid
E.g. 2(CH3CO)_2 O + C6H5OH => CH3COOC6H5 + CH3CHOOH
Ethanoic Anhydride + Phenol => phenylethanoate + ethanoic acid
Reagents
-Phenol

Question 4

Primary Amide => Secondary Amide
Equation
Reagents

Answer 4

Equation
- primary amide + acyl chloride => secondary amide + ammonium salt
E.g. Ethanoyl chloride+ 2(methylamine) => methylammoium chloride (CH3NH3+Cl-) + N-methylethanamide (CH3CONHCH3)
Reagents

Question 5

Alkane =>Haloalkane
Equation

Draw mechanism

Answer 5

Equation
- CH4 + Br2 => CH3Br + HBr

Type of reaction
-Radical Substitution
