JEE Advanced2017ChemistryHaloalkanes and HaloarenesActual
For the following compounds the correct statement(s) with respect to nucleophilic substitution reactions is(are)
Options
- AI and II follow S N 2 mechanism
- BThe order of reactivity for I, III and IV is: IV > I > III
- CI and III follow S N 1 mechanism
- DCompound IV undergoes inversion of configuration
Correct answer
A. I and II follow S N 2 mechanism
Step-by-step solution
(i) I and II follow S N 2 mechanism as they are primary (ii) Reactivity order IV > I > III (iii) I and III follows S N 1 mechanism as they form stable carbocation (iv) Compound IV undergoes inversion of configuration.
