Chapter 13, Problem 35PP

Interpretation Introduction

Interpretation: The unknown product of the given reaction to be predicted.

Concept Introduction:

Useful reagents:

1. 1. $\text{NaH}$: A strong base which abstract the acidic proton and generate alkoxide ion.

Intramolecular ${\text{S}}_{\text{N}}\text{2}$ reaction: The groups like esters, sulfides, carboxylates, ethers, amines or alkoxide also assist substitution reactions through neighboring group participation. All must possess an electron-rich heteroatom with a lone pair of electron that can be used to form the cyclic intermediates or cyclic products.

To Identify: The reagents for the transformation of the given reaction.
