Benzene reacts with CH3Cl in the presence of anhydrous AlCl3 to form:
1. | Toluene | 2. | Chlorobenzene |
3. | Benzylchloride | 4. | Xylene |
The reagent used in the above conversion is:
1. Cr2O3
2. Alc. KOH
3. Red hot Fe
4. NaNH2/liq.NH3
The reaction of toluene with Cl2 in presence of FeCl3 gives ‘X' and the reaction in presence of light gives 'Y'. 'X' and 'Y' are respectively:
1. | X= Benzal chloride, Y= o-chlorotoluene |
2. | X= m-chlorotoluene, Y= p-chlorotoluene |
3. | X= o and p-chlorotoluene, Y= trichloromethyl benzene |
4. | X= Benzyl chloride, Y= m-chlorotoluene |
