3. 

4. C₆H₅Br

Q. Columns 1, 2 and 3 contain starting materials, reaction conditions, and type of reactions, respectively:
$\begin{array}{ccc}\text{Column 1}& \text{Column 2}& \text{Column 3}\\ \text{(I) Toluene}& \left(i\right)NaOH/B{r}_2& \text{(P) Condensation}\\ \text{(II) Acetophenone}& \left(ii\right)B{r}_2/hv& \text{(Q) Carboxylation}\\ \text{(III) Benzaldehyde}& \left(iii\right)(C{H}_{3}CO{)}_{2}O/C{H}_{3}COOK& \text{(R) Substitution}\\ \text{(IV) Phenol}& \left(iv\right)NaOH/C{O}_2& \text{(S) Haloform}\end{array}$
The only CORRECT combination in which the reaction proceeds through radical mechanism is:

1. (I) (ii) (R)
2. (II) (iii) (R)
3. (III) (ii) (P)
4. (IV) (i) (Q)

Q. The reaction of toluene with $C{l}_2$ in presence of $FeC{l}_3$ gives X and reaction in presence of light gives Y. Thus, X and Y are

1. X = benzyl chloride, Y = m-chlorotoluene
2. X = benzal chloride, Y = o-chlorotoluene
3. X = m-chlorotoluene, Y = p-chlorotoluene
4. X = o-and p-trichloromethyl benzene
