SR Benzene 3M

Question 1

Benzene => Alkyl Benzene
Equation
Type of reaction
Conditions 
Reagents

Answer 1

Equation
Benzene + Haloalkane => Alkylbenzene + HX
AlCl3

Type of reaction
Alkylation

Conditions
Presence of a halogen carrier catalyst to generate the electrophile
Eg AlCl3 or FeCl3

Reagents
Haloalkane

*making more C-C bonds, the number of carbons in the molecule is increased

Question 2

Benzene => Phenylalkanone
Equation
Type of reaction
Conditions 
Reagents

Answer 2

Equation
Benzene+ acyl chloride => phenylalkanone + HCl
Eg Benzene + Ethanoyl Chloride => Phenylethanone + HCl

Type of reaction
Electrophilic Substitution

Reagents
Acyl Chloride

• makes C-C bonds
• used in perfume Industry

Question 3

Benzene => Nitrobenzene 
Equation
Type of reaction
Conditions 
Reagents

Answer 3

Equation
Benzene + HNO3 => nitrobenzene + H20

Type of reaction
Nitration
Electrophillic Substitution

Conditions
Con H2SO4 Catalyst
50C any higher leads to further Substitution. Temp control is key in organic chemistry, use water bath to maintain temperature . 70C for dinitrobenzene

Reagents
HNO3

Question 4

Benzene => Bromobenzene
Equation
Type of reaction
Conditions 
Reagents 
Draw mechanism

Answer 4

Equation
FeBr3/AlBr3
Benzene + Br_2 => Bromobenzene + HBr

Type of reaction
Electrophillic Substitution
Bromination
Halogenation

Conditions
Room temperature
Halogen Carrier catalyst nah happen without it. It can be generated in situ so metal + halogen

Reagents
Br_2

Question 5

Answer 5

Equation
FeCl3/AlCl3
Benzene + Cl_2 => chlorobenzene + HCl

Type of reaction
Electrophillic Substitution
Chlorination
Halogenation

Conditions
Room temperature
Halogen Carrier catalyst nah happen without it. It can be generated in situ so metal + halogen

Reagents
Cl_2
