Consider the following statements:

1. Toluene may be oxidised to benzaldehyde by the use of ${\mathrm{CrO}}_2{\mathrm{Cl}}_2$.

2. Nitration of benzene is electrophilic addition reaction.

3. The function of anhydrous ${\mathrm{AlCl}}_3$ in Friedel-Craft reaction is to absorb water.

4. Nitration of benzene is carried out by a mixture of conc. ${\mathrm{HNO}}_3$ and conc. ${\mathrm{H}}_2{\mathrm{SO}}_4$.

The wrong statements are
