The correct order of the following compounds showing increasing tendency towards nucleophilic substitution reaction is :
Option: 1 (iv) < (i) < (ii) < (iii)
Option: 2 (i) < (ii) < (iii) < (iv)
Option: 3 (iv) < (i) < (iii) < (ii)
Option: 4 (iv) < (iii) < (ii) < (i)
Reactivity -M group present at O/P position.
As the number of -M group increases the reactivity towards nucleophilic substitution reaction increases.
Correct order: (i) < (ii) < (iii) < (iv)
Therefore, the correct answer is Option (2).
