Chapter 11: Q 11-11-42 E-a (page 350)

Which reactant in each of the following pairs is more nucleophilic? Explain.

a) NH2-or NH3

Short Answer

Expert verified

NH2-

Step by step solution

01

Nucleophile

In chemistry, nucleophiles are negatively charged ions or neutral species with only one electron available for bonding.

02

Rules to identify more nucleophilic species

  1. Nucleophile attacking the same atom then nucleophilicity is same as basicity that more basic species is more nucleophilic in nature.
  2. Nucleophilicity increases in going down in a group of the periodic table.
  3. A negatively charged nucleophile is more nucleophilic than a neutral nucleophile due to a negative charge.
03

More nucleophiles among  NH2- or NH3

On the basis of:

Rule 1: Nucleophile attacking the same atom then nucleophilicity is same as basicity that more basic species is more nucleophilic in nature.

Rule3: A negatively charged nucleophile is more nucleophilic than a neutral nucleophile due to a negative charge.

NH2-is more nucleophilic than NH3
