Chapter 6, Problem 16PP

Interpretation Introduction

Interpretation:

In the given nucleophiles, thestronger nucleophile in a polar aprotic solvent is to be classified.

Concept introduction:

Electrophiles are electron-deficient species, which has positive or partially positive charge. Lewis acids are electrophiles, which accept electron pair.

Nucleophiles are electron-rich species, which has negative or partially negative charge. Lewis bases are nucleophiles, which donate electron pair.

A chemical species thathas the tendency to donate an electron pair to an electrophile in order to form a chemical bond is known as nucleophile.

The polar solvent in absence of acidic is known as polar aprotic solvent.

The polar solvent in presence of acidic hydrogen, which is bonded to oxygen or nitrogen atom in order to form hydrogen bonding is known as polar protic solvent.

If lone pair of electron is present on more electronegative atom, it cannot donate electron pair easily. It is considered as weak nucleophile.

Less electronegative atom can easily donate electron.

If a nucleophile can easily donate electron to electrophile then it is considered as strong nucleophile.
