The oxidation of benzene by V₂O₅ in the presence of air produces:

A compound among the following that does not undergo Friedel-Craft's reaction easily is-

1. Cumene               

2.  Xylene

3. Nitrobenzene         

4. Toluene

Nitrobenzene can be prepared from benzene by using a mixture of conc. HNO₃ and conc.

H₂SO₄. In the mixture, nitric acid acts as a/an-

1. Reducing agent

2. Acid

3. Base

4. Catalyst

3.		4.

 The compounds among the following that can be generated by Friedel craft acylation is/are -

I.
II.
III.
IV.

Cyclopentadiene is much more acidic than cyclopentane, beacuse -

1. Cyclopentadiene has conjugated double bonds.

2. Cyclopentadiene has both sp² and sp³ hybridized carbon atoms.

3. Cyclopentadiene is a strain-free cyclic system.

4. Cyclopentadienyl anion ion, the conjugate base of cyclopentadiene, is an aromatic species and hence has higher stability.

The product (B) in the above-mentioned reaction is-
