(a) Interpretation: For each step of the given unimolecular nucleophilic substitution S N 1 reaction, all electron-rich sites and electron-poor sites are to be identified. Concept introduction: An atom with partial or full negative charge is called an electron-rich site whereas an atom with partial or full positive charge is called an electron-poor site. An electron-rich atom has a lone pair of electrons whereas an electron-poor atom lacks an octet. In an elementary step, electrons tend to flow from an electron-rich site to an electron-poor site.

Question

Chapter 7, Problem 7.46P

Interpretation Introduction

(a)

Interpretation:

For each step of the given unimolecular nucleophilic substitution SN1 reaction, all electron-rich sites and electron-poor sites are to be identified.

Concept introduction:

An atom with partial or full negative charge is called an electron-rich site whereas an atom with partial or full positive charge is called an electron-poor site. An electron-rich atom has a lone pair of electrons whereas an electron-poor atom lacks an octet. In an elementary step, electrons tend to flow from an electron-rich site to an electron-poor site.

Interpretation Introduction

(b)

Interpretation:

Appropriate curved arrows are to be drawn to show the bond formation and bond breaking that occur in each step of the given unimolecular nucleophilic substitution SN1 reaction.

Concept introduction:

In an elementary step, electrons tend to flow from an electron-rich site to an electron-poor site. One curved arrow is drawn from the lone pair of an electron-rich atom to the H attached to the electron-poor site to show the formation of a bond. A second curved arrow is drawn starting from the middle of the broken bond to the atom on which the lone pair ends up, to indicate the breaking of the bond.

Interpretation Introduction

(c)

Interpretation:

Each step of the given unimolecular nucleophilic substitution SN1 reaction is to be named.

Concept introduction:

An elementary step in which a proton is transferred from an electron-poor site to an electron-rich site and one bond is broken and another is formed simultaneously is called the proton transfer step. An elementary step in which only single bond is broken and both electrons from that bond end up on one of the atoms initially involved in the bond is called the heterolysis step. An elementary step in which a single covalent bond is formed between the electron-rich site and the electron-poor site is called the coordination step.
