The decreasing order of rate of reaction for the following compounds towards S N 2Th (bimolecular nucleophilic substitution with tetrahedral intermediate) reaction is (i) (ii) (iii) (iv)
Options
- AI > II > III > IV
- BII > III > I > IV
- CIII > II > IV > I
- DII > III > IV > I
Correct answer
D. II > III > IV > I
Step-by-step solution
Reactivity order of compounds towards S N 2Th depend on partial possitve charge present of carbon which is increases due to − I effect hence the order S N 2Th is
