The oxidation of benzene by V2O5 in the presence of air produces?
1. Benzoic anhydride
2. Maleic anhydride
3. Benzoic acid
4. Benzaldehyde
A compound that cannot give Friedel-Craft’s reaction is:
1. | Xylene | 2. | Nitrobenzene |
3. | Toluene | 4. | Cumene |
The order of decreasing reactivity towards an electrophilic reagent, for the following:
(i) Benzene (ii) Toluene
(iii) Chlorobenzene and
(iv) Phenol
would be:
1. (i) > (ii) > (iii) > (iv)
2. (ii) > (iv) > (i) > (iii)
3. (iv) > (iii) > (ii) > (i)
4. (iv) > (ii) > (i) > (iii)
