                     <55 °C
Product : benzene with R and NO2 and H2O 
                 NO2 ( Ortho and para)

Question 2

Halogenation of methylbenzene

Answer 2

Reagent : Cl2 in CCl4
Condition : anhydrous AlCl3
                     Room temp
Product : benzene ring with R and CL and H2O
                  CL ( ortho and para)

Question 3

Fridel- Crafts Alkylation of methylbenzene

Answer 3

Reagent : RX
Condition : Anhydrous AlCl3
                     Room temp
Product : benzene ring with CH3 and R and HCl
Ortho and para

Question 4

Friedel-Crafts Acylation of methylbenzene

Answer 4

Reagent : RCOCl
Condition : anhydrous AlCl3
Product : benzene ring with CH3 and R (2, 4)

Question 5

Free radical substitution of methylbenzene

Answer 5

Reagent :Cl2

Condition : UV light

Question 6

Oxidation of methylbenzene

Answer 6

Reagent : Acidified potassium manganate(VII) solution
Condition : Reflux
Product: benzoic acid for CH3
Benzoic acid and CO2 for R

Question 7

How to differentiate between methylbenzene and other alkylbenzene

Answer 7

Using oxidation my acified potassium manganate(VII) solution under reflux
Methyl benzene will not produce CO2
Other alkylbenzne will produce CO2
