The correct order of the following compounds showing increasing tendency towards nucleophilic substitution reaction is:

  1. (iv) < (i) < (ii) < (iii)
  2. (i) < (ii) < (iii) < (iv)
  3. (iv) < (i) < (iii) < (ii)
  4. (iv) < (iii) < (ii) < (i)

Solution

For nucleophile substitution in aromatic halides

Correct order is:

(i) < (ii) < (iii) < (iv)

More No. of NO2 substituted aromatic halide, increase the rate of nucleophile substitution reaction in aromatic halides.
