The decreasing order of rate of reaction for the following compounds towards ${S}_{N} \text{2Th}$ (bimolecular nucleophilic substitution with tetrahedral intermediate) reaction is

(i)&
(ii)&
(iii)&
(iv)&

Step-by-step solution

Reactivity order of compounds towards ${S}_{N} \text{2Th}$ depend on partial possitve charge present of carbon which is increases due to $- \text{I}$ effect hence the order ${S}_{N} \text{2Th}$ is
