Answer

(3) [figure]

Solution

(i) In chlorination, -C2H5 (activating, o/p-directing) and -NO2 (deactivating, m-directing) both direct Cl to the carbon ortho to -C2H5 (meta to -NO2).

(ii) Sn/HCl reduces -NO2 to -NH2.

(iii) NaNO2/HCl at 273–278 K converts -NH2 into the diazonium salt -N2 Cl .

(iv) KI replaces -N2 by -I.
