Chapter 2: Q4. (page 61)

Question: Draw additional resonance structures for each anion.

Short Answer

Expert verified

Answer

The additional resonance structure for each anion is shown below.

Step by step solution

01

Definition of resonance

Resonance is defined as the way of representing the delocalization of electrons in a molecule.

02

Advantages of resonance

A structure capable of showing resonance has higher acidity as compared to those structures having no resonating structures. The stability of the compound also increases as electron density is distributed throughout the structures.

The resonance structure for each anion is shown below.

Resonance in a

Resonance in b

Resonance in c
