Nitrobenzene on reaction with conc. HNO₃/H₂SO₄ at 80-100$°$C forms -

1. 1,2-Dinitrobenzene

3. 1,4-Dinitrobenzene

4. 1,2,4-Trinitrobenzene

The reaction of toluene with ${\mathrm{Cl}}_2$ in the presence of ${\mathrm{FeCl}}_3$ gives 'X' and reaction in presence of light gives 'Y'. Thus, 'X' and  'Y' are

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 = benzal chloride, Y = m-chlorotoluene

RCOCl and ${\mathrm{AlCl}}_3$ are used in the Friedel-Crafts reaction.
The electrophile among the following is:

1. ${\mathrm{Cl}}^{+}$                                       

2. RCOCl

3. $\mathrm{R}\stackrel{+}{\mathrm{C}}$O                                     

4. ${\mathrm{R}}^{+}$

The most reactive of these compounds towards sulphonation is
