Chapter 6.7, Problem 6.18E

Interpretation Introduction

Interpretation: The product of the reaction of 1-chloro-6-iodohexane with one equivalent of sodium methylselenide should be predicted.

Concept Introduction:

Facility of S_N² displacements depends on the nature of the leaving group, reactivity of nucleophile and the structure of the alkyl portion of the substrate. Higher the leaving group ability to be displaced, easier the S_N² displacement reaction. For halogens, leaving group ability increases down the group.${\text{F}}^{-}{\text{ > Cl}}^{-}{\text{ > Br}}^{-}{\text{ > I}}^{-}$
