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

Options

  1. A(iv) < (i) < (ii) < (iii)
  2. B(i) < (ii) < (iii) < (iv)
  3. C(iv) < (i) < (iii) < (ii)
  4. D(iv) < (iii) < (ii) < (i)

Correct answer

B. (i) < (ii) < (iii) < (iv)

Step-by-step solution

For nucleophile substitution in aromatic halides Correct order is: (i) < (ii) < (iii) < (iv) More No. of NO 2 substituted aromatic halide, increase the rate of nucleophile substitution reaction in aromatic halides.
