Chapter 20.3, Problem 4CC

Interpretation Introduction

Interpretation:

The concept of constitutional isomerism and acidic nature of the given set of compounds should be identified.

Concept introduction:

Acidity:

Acidity of the compound is the measure of strength of the acid.  If the acid forms a more stable conjugate base after deprotonation then that acid is said to be more acidic.  The number and the strength of electron withdrawing group attached to the carbon that bears the removable proton determine the acidity of compound.

Isomer:

“Compounds whose molecular formula is same but the arrangement of atoms are   different in their molecule and they differ in chemical structure. They distinct in chemical and physical properties also”

Types:

Isomerism are classified into two types

1. Constitutional or Structural isomerism

2. Stereo or Spatial isomerism

Constitutional or Structural isomerism:

Compounds which have same molecular formula are having different connectivity of atoms and with different structure. These isomers can also be referred as “structural isomers”. Structural isomers have different IUPAC names.
